In recent years, there has been a big data revolution in smart cities dues to multiple disciplines such as smart healthcare, smart transportation, and smart community. However, most services in these areas of smart cities have become data-driven, thus generating big data that require sharing, storing, processing, and analysis, which ultimately consumes massive amounts of energy. The accumulation process of these data from different areas of a smart city is a challenging issue. Therefore, researchers have started aiming at the Internet of vehicles (IoV), in which smart vehicles are equipped with computing and storage capabilities to communicate with surrounding infrastructure. In this paper, we propose a subcategory of IoV as the Internet of buses (IoB), where public buses enable a service as a data carrier in a smart city by introducing a neural network-based sustainable data dissemination system (NESUDA), where opportunistic sensing comprises delay-tolerant data collection, processing and disseminating from one place to another place around the city. The objective was to use public transport to carry data from one place to another and to reduce the traffic from traditional networks and energy consumption. An advanced neural network (NN) algorithm was applied to locate the realistic arrival time of public buses for data allocation. We used the Auckland transport (AT) buses data set from the transport agency to validate our model for the level of accuracy in predicted bus arrival time and scheduled arrival time to disseminate data using bus services. Data were uploaded onto buses as per their dwelling time at each stop and terminals within the coverage area of deployed RSU. The offloading capacity of our proposed data dissemination system showed that it could be utilized to effectively complement traditional data networks. Moreover, the maximum offloading capacity at each parent stop could reach up to 360 GB with a huge saving of energy consumption.

Small Cells (SCs) mounted on top of Unmanned Aerial Vehicles (UAVs) can be used to boost the radio capacity in hotspot zones. However, UAV-SCs are subject to tight battery constraints, resulting in frequent recharges operated at the ground sites. To meet the UAV-SCs energy demanded to the ground sites, the operator leverages a set of Solar Panels (SPs) and grid connection. In this work, we demonstrate that both i) the level of throughput provided to a set of areas and ii) the amount of energy that is exchanged with the grid by the ground sites play a critical role in such UAV-aided cellular network. We then formulate the J-MATE model to jointly optimize the energy and throughput through revenue and cost components. In addition, we design the BBSR algorithm, which is able to retrieve a solution even for large problem instances. We evaluate J-MATE and BBSR over a realistic scenario composed of dozens of areas and multiple ground sites, showing that: i) both J-MATE and BBSR outperform previous approaches targeting either the throughput maximization or the energy minimization, and ii) the computation time and the memory occupation of BBSR are reduced up to five orders of magnitude compared to J-MATE.

One of the main challenges of operating a smart city (SC) is collecting the massive data generated from multiple data sources (DSs) and transmitting them to the control units (CUs) for further data processing and analysis. These ever-increasing data demands require not only more and more capacity of the transmission channels but also results in resource over-provision to meet the resilience requirements, thus the unavoidable waste as a result of the data fluctuations throughout the day. In addition, the high energy consumption (EC) and carbon discharge from these data transmissions posing serious issues to the environment we live in. Therefore, to overcome the issues of intensive EC and carbon emission (CE) of massive data dissemination in SCs, we propose an energy-efficient and carbon reduction approach by using the daily mobility of the existing vehicles as an alternative communications channel to accommodate the data dissemination in SCs. To illustrate the effectiveness and efficiency of our approach, we take the Auckland City in New Zealand as an example, assuming massive data generated by various sources geographically scattered throughout the Auckland region, to the control centres located in the city. Results obtained show that our proposed approach can provide up to four times faster transferring the large volume of data by using the existing daily vehicles' mobility, than the conventional transmission network. Moreover, our proposed approach offers about 32% less EC and CE than that of conventional network transmission approach.

Significant technological advancements over the last two decades have led to enhanced accessibility to computing devices and the Internet. Our society is experiencing an ever-growing integration of the Internet into everyday lives, and this has transformed the way we obtain and exchange information, communicate and interact with one another as well as conduct business. However, the term ‘Internet addiction’ (IA) has emerged from problematic and excessive Internet usage which leads to the development of addictive cyber-behaviours, causing health and social problems. The most commonly used intervention treatments such as motivational interviewing, cognitive-behavioural therapy, and retreat or inpatient care mix a variety of psychotherapy theories to treat such addictive behaviour and try to address underlying psychosocial issues that are often coexistent with IA, but the efficacy of these approaches is not yet proved. The aim of this paper is to address the question of whether it is possible to cure IA with the Internet. After detailing the current state-of-the-art including various IA definitions, risk factors, assessment methods and IA treatments, we outline the main research challenges that need to be solved. Moreover, we propose an Internet-based IA Recovery Framework (IARF) which uses AI to closely observe, visualize and analyse patient’s Internet usage behaviour for possible staged intervention. The proposal to use smart Internet-based systems to control IA can be expected to be controversial. This paper is intended to stimulate further discussion and research in IA recovery through Internet-based frameworks.

The emerging smart city paradigm e.g., intelligent transport, smart grid and participatory sensing etc. is to advance the quality, performance and experience of urban citizten services through greater connectivity. This paradigm needs to collect data from citizens, various devices and assets that could be monitored, processed and analysed for the city governers to make better decision and also more efficiently manage those assests and resources. While the telecommunication and Internet are progressively being over-burdened and congested by the growing data transmission demands. To keep expanding the telecommunications and Internet infrastructures to accomodate these intensive data demands is costly and also the associated energy consumptions and carbon emissions could at long last wind up genuinely hurting the environment. To face this issue in the coming era of big data, we envision it will be best to utilize the established urban transport and road infrastructure and existing daily massive vehicular trips, to complement traditional option for data transmission. After detailing the current state-of-the-art, we consider the main challenges that need to be faced. Moreover, we define the main pillars to integrate the telecommunications and transport infrastructures, and also a proposal for the future urban network architecture.

The Internet has evolved as a critical booster for the economic, social and technical development of human society. Almost half of the world’s population is unfortunately missing out due to the lack of access to the Internet. Such users are mainly those living in rural and low-income areas. Various strategies and approaches for improving the Internet’s accessibility are available, each with a different set of benefits, costs, and risks. It is important to choose solutions from these feasible options that promise to promote the efficiency as well as the sustainability of the ‘Internet Ecosystem’. In this paper, we propose a new model of sustainable connectivity that integrates three factors (affordability, social shareability, and geographical network coverage) that must be considered in the selection and design of Internet access solutions. In addition, we develop a hypergraph-based network graph solution that illustrates the relationship among the three factors. Then, we use Coloured Petri Nets (CPNs) to model and simulate the possible Internet access solutions and also interplay those three factors to study how they impact the overall network connectivity performance. Our initial results have revealed how sustainable Internet connectivity behaves as a function of the affordability, social interaction, and geographical network coverage and investigates how these factors could be leveraged to provide different network connectivity and Internet access solutions.

The emerging cyber-physical paradigm endeavours to unite all the physical objects embedded with electronics, software, sensors, and network connectivity to allow more direct interactions and information sharing between the physical and cyber worlds. While these massively connected devices and their associated communications can exponentially increase the data generation, transmission, and processing which consume a huge amount of energy and finally end up with harming the environment seriously. In this paper, we propose a solution for energy efficient data dissemination by using the opportunistic device-to-device (D2D) communications. Each sender can decide either use network infrastructure or through encountering the end-users according to the quality of service (QoS) requirements of each data demand and also the mobility behaviors of the users. These decisions are based on the time and location- traces of daily mobility routines and related activities of users and their social relationship. The case study, based on the similarity analysis of the mobility traces, has confirmed the rich opportunities for encountering among people, thus the proposed approach has great promises to reduce the energy consumption of big data dissemination.

With the growing popularization of Electric Vehicles (EVs), charging management has become an increasingly important research problem in smart cities. Different from plug-in charging technology, we alternatively enable the battery switch technology to provide fast EV charging (reduce the service waiting time from tens of minutes to a few minutes), by facilitating the switchable (fully-recharged) batteries maintained at CSs and also the batteries cycling procure to refresh their availability. Nevertheless, potential hot spot may still happen at CSs, due to running out of switchable batteries as well as long batteries charging queue. With this concern, we next propose a reservation based EV charging management scheme to alleviate such situation, considering EVs' anticipated charging reservations (including arrival time, expected charging time) to coordinate EVs' charging plans. Results under the Helsinki city scenario with realistic EV and CS characteristics show the advantage of our enabling technology, in terms of minimized waiting time for the battery switch as the benefit of EV drivers, and higher number of batteries switched as the benefit of CSs.

In September 2015, the United Nations General Assembly accepted the 2030 Development Agenda, which has included 92 paragraphs, and the Paragraph 91 defined 17 sustainable development goals (SDGs) and 169 associated targets. The goal of this paper is to discover the correlations among SDGs and information and communications technologies (ICTs). This paper discusses the roles and opportunities that ICTs play in pursuing the SDGs. We identify a number of research gaps to those three pillars, social, economic, and environmental perspectives, of sustainable development. After extensive literature reviews on the SDG-related research initiatives and activities, we find that the majority of contributions to SDGs recognized by the IEEE and ACM research communities have mainly focused on the technical aspects while there are lack of the holistic social good perspectives. Therefore, there are essential and urgent needs to raise the awareness and call for attentions on how to innovate and energize ICTs in order to best assist all nations to achieve the SDGs by 2030.

The digital divide refers to the gap between those who have access to modern information and communications technology (ICT) and those who do not or have constrained access. This technology could include telephones, television, computers and the Internet. The arrival of high-speed Internet connectivity to the Kingdom of Tonga continues to bring opportunities such as business growth and jobs creation; however, there is also a growing digital divide affecting the country and other regions of the world. These motivate us to debate and seek the best way to reduce the divide in Tonga. Much of the research on this area focuses on the accessibility to the technologies, while some works have addressed the inequality in the ability and skills to use the technology. Motivated by the United Nations' sustainable development goals (SDGs), especially Goal 9 on Industry, Innovation and Infrastructure and Goal 10 on Reduced Inequalities, we examine both perspectives of digital divide in Tonga. Moreover, we introduce the most recent broadband technologies and discuss their potential to enable Tonga's digital transformation from the perspectives of reliability, security and affordability. We then envision a sustainable multi-tenancy broadband infrastructure to integrate various access technologies in order to offer multi-services, which can best accommodate Tongan's various ICT needs according to their different geographical and socio-economic characteristics. This paper intends to contribute to the current debate, and stimulate further discussion and research on reducing the digital divide in Tonga.

The advancement in the field of information and communication technology has generated a great deal of information that was not possible to access earlier. Healthcare systems are one of the most beneficial applications using wireless medical sensor technologies, which can facilitate patient care within homes, hospitals, clinics, disaster sites, and the open environment. The integration and sharing of such information can contribute significantly to a better understanding of patients' health conditions and therefore to improving the quality of healthcare provided to them. However, in order to achieve sufficient levels of collaborative use of information among healthcare-related practitioners, there is a need to overcome a number of issues such as privacy and interoperability, among others. This chapter discusses two of the main challenges encountered before healthcare information systems can collaboratively share patients' records, namely privacy and interoperability.

In this chapter we firstly review the state of the art of the data center networks (DCNs) topological structures and explain the challenges in this field, which motivates our work. Then we propose a method for evaluating the topological metrics related to network robustness and node centrality so as to identify the most critical nodes and links in DCNs, as well as measuring the overall DCN performance such as throughput, latency, packet drop ratio according to the various faults occurred in the network. Moreover, we have identified the energy consumption behaviours according to the change of DCN’s internal structure. Our simulation studies showed that the DCN topology and traffic load have significant impact on its overall energy consumption and also on other network-related performance aspects.

The traditional world has transformed into a digital society where almost anything can be accessed from anywhere. However, this digital society is responsible for an explosive growth of high-volume, high-velocity and high-variety information assets, with high demand for “Big Data”. A Software Defined Connectivity (SDC) is an emerging paradigm, which promises to simplify network management, to provide the flexibility to program the network through centralized network control by providing new abstractions in networking with all real objects for reliable and energy efficient data transmission. In a SDC architecture, the connectivity controller decides the forwarding rules as per the demands and objectives of users when transmitting information to the intended destination through either internet or existing transport infrastructure. The key idea is to have flexibility in the network to utilize existing transport infrastructure to shift traffic from the internet towards public bus services as per the current users requirements. The numerical studies reported in this paper confirm that this new opportunity helps to achieve efficient resource utilization and high performance with significant savings of energy.

The New Zealand Government has set the goals of having 99% of Kiwis able to access broadband with peak speeds of at least 50 Megabits per second (Mbps) by 2025, and with the remaining 1% able to access broadband with rates of at least 10 Mbps. There is an interesting question to be raised: is it possible to achieve these goals earlier? Inspired by the United Nations' Sustainable Development Goals (SdGs), especially the SDG 17 of Partnerships for the goals, we propose bottom-up and top-down partnerships based on a sustainable research enlightened MahiTahi approach to pursue the New Zealand rural connectivity goals. In Maori, MahiTahi means “collaboration” which best represents the key design and implementation principles embedded into our approach. It aims to address the three dimensional challenges of rural connectivity including the collaboration among various network access technologies to advance geo-reachability; the collaboration among different stakeholders to optimize social and economic reachabilities, as well as the collaboration among national and international knowledge societies from multiple disciplines to maximize knowledge reachability. Rather than providing a final solution, this paper aims to inspire and invite wider discussions and dialogues to collaboratively seek out a timely holistic solution so as to assist the Government to achieve Her goals as earliest as possible.

One of the main issues for a smart city is the data aggregation from various data sources to the central control units for storage and analysis. While the core networks are winding up progressively over-burden, the cost of keeping up and extending the networks to oblige the big data of these smart cities stays high. Moreover, the utilization of these systems continues expanding the energy consumptions. Consequently, the carbon emissions amid this procedure could at long last wind up genuinely hurting the environment. In order to overcome the problems of congested networks, energy consumption, and carbon emissions we propose an energy efficient data dissemination framework. The idea is to utilize the city existing public transport infrastructure to pick up and deliver the big data from designated pick-up points and data centers. Two numerical studies evaluated in this paper confirm the noteworthy cost and energy savings can be obtained by utilizing the existing vehicle volume on the road for big data dissemination in the smart city. The analysis of energy cost and carbon emissions using the traditional min-cost flow problem is also included.

The Device-to-Device communication (D2D) is believed to be one of promising paradigm for 5G wireless communication networks. D2D networks are based on a distributed peer to peer (P2P) network architecture where the nodes are self-organized. Moreover, as the devices are controlled by humans, their behaviours become unpredictable. Trust and reputation management (TRM) emerges as a significant research problem to tackle the security issues in D2D networks. Recently, there is a rapid growth of literature related to TRM but mainly focus their attention on trust modelling and quantification, so as to effectively detect and avoid various malicious attacks or selfish behaviours. However, there are only very limited existing works on the impact of the underlying network structure on overlay dynamic trust behaviours. The network trust behaviour is not merely a function of trust modes, but also a network-wide activity. In this paper, we propose the concept of ”Network-Trustworthiness-as-a-Service” (NTaaS) - a network trustworthiness evaluation framework for the trustworthiness of the networks from global point of view. We also evaluate the evaluation framework through a thorough simulation study comparing different network topologies. The study will validate the trustworthiness evaluation framework, and thus present a guideline to evaluate network trustworthiness and network structure optimisation.

Nowadays, at least two billion people are experiencing a complete lack of wireless cellular network coverage. These users live in rural areas and low-income regions, where network operators are not keen to invest, mainly due to high capital expenditure and operational expenditure costs, as well as the scarcity of electricity from the grid. We tackle this challenge by proposing a 5G network explicitly designed to serve rural and low-income areas. Our solution investigates the possibility of mounting remote radio heads on top of unmanned aerial vehicles, as well as large cells (LCs) to increase the coverage range. In addition, 5G nodes are powered by solar panels and batteries. Preliminary results, obtained over three representative case studies located in Italy, Cook Islands, and Zimbabwe, show that providing connectivity in rural and low-income areas by means of the proposed 5G architecture is feasible. At the same time, we also show that the monthly subscription fee paid by the users can be kept sufficiently low, that is, less than €1/month in low-income areas, and around €11/month in rural regions.

Immediately after a disaster, the normal telecommunication infrastructure, including wired and wireless networks, is often seriously compromised and cannot guarantee regular coverage and reliable communications services. These temporarily-missing communications capabilities are crucial to rescuers and affected citizens as the responders need to effectively coordinate and communicate to minimize the loss of lives and property. A cyber-physical system (CPS) is composed of integrated communication, computation and physical objects, and cyber-physical vehicle systems (CPVSs) are an emerging field due to the rapid advancements on real-time computing, mobile communications and autonomous control in intelligent transport systems. In this paper, we propose a cyber-physical buses-and-drones mobiLe edge infrastructure (AidLife) for disaster emergency communications, which aims at a rapidly deployable resilient system capable of supporting flexible communications to serve large-scale disaster situations by utilizing the existing public transport system. In particular we envision a proposal where public buses can be recruited to temporarily host portable base station (BS) and computation units as well as power resources so as to form a buses-based mobile edge infrastructure, and also accommodate drones to extend their coverage to hard-to-reach areas. Our preliminary results show that the AidLife system can guarantee a good coverage to users, even when a large number of normal BSs that are damaged.

The advancements of Information and Communications Technologies (ICT) have contributed to an explosive growth of high-volume, high-velocity and high-variety information assets, and the era of Big Data has emerged. The infrastructure-based networks are becoming increasingly overloaded, while the cost of maintaining and expanding the infrastructure to accommodate the Big Data communications remains high. In addition, the use of these networks keeps increasing energy demand and consumptions. As a result, the carbon emission during this process could finally end up seriously harming the environment. Our approach consists of offloading delay-tolerant data from the wired and wireless networks towards the existing public transport infrastructure, including buses, trams, trains, and aeroplanes by exploring their optimal temporal-spatial resource efficiency. The two numerical studies reported in this paper confirm the significant energy and cost savings available by utilizing the scheduled public transport networks for data dissemination while still guaranteeing data delivery.
