In this paper, a coordinated multipoint joint transmission (CoMP-JT) framework at mmWave for a cyclic prefix (CP)-free multiuser OFDM wireless communication system is developed and analyzed. The aim is to provide high-quality service to cell-edge users; otherwise, the cell-users would suffer from significant signal degradation due to undesired interference. The impact of complex Hadamard transform with block diagonalization channel precoding for multiuser interference reduction and designed subcarrier mapping for out-of-band (OOB) reduction are investigated. In addition, the paper studied the input back-off-aided high-power amplifier for peak-to-average power ratio (PAPR) reduction and forward error correction channel coding for improved bit error rate (BER) for cell-edge users at mmWave frequencies. Moreover, signal-to-interference-noise ratio and ergodic achievable rate are estimated both in the presence and absence of CoMP-JT-based transmission technique to verify their significance in terms of transmitted power. Numerical investigations showed an OOB reduction of 312 dB, PAPR reduction from 17.50 dB to 7.66 dB, and improved BER of 1×103 in 16-QAM for a signal-to-noise ratio of −6 dB. Hence, the simulation results demonstrated the effectiveness of the developed system.

The mobile relaying technique is a critical enhancing technology in wireless communications due to a higher chance of supporting the remote user from the base station (BS) with better service quality. This paper investigates energy-efficient (EE) mobile relaying networks mounted on the unmanned aerial vehicle (UAV) while the unknown adversaries try to intercept the legitimate link. We aim to optimize robust transmit power, both UAV and BS along, with relay hovering path, speed, and acceleration. The BS sends legitimate information, which is forwarded to the user by the relay. This procedure is defined as information-causality-constraint (ICC). We jointly optimize the worst-case secrecy rate (WCSR) and UAV propulsion energy consumption (PEC) for a finite time horizon. We construct the BS-UAV, the UAV-user, and the UAV-adversary channel models. We apply the UAV PEC considering UAV speed and acceleration. We derive EE UAV relay-user maximization problem in the adversarial wireless networks at last. While the problem is non-convex, we propose an iterative and sub-optimal algorithm to optimize EE UAV relay with constraints, such as ICC, trajectory, speed, acceleration, and transmit power. First, we optimize both BS and UAV transmit power and hovering speed for known UAV path planning and acceleration. Using the optimal transmit power and speed, we obtain the optimal trajectory and acceleration. We compare our algorithm with existing algorithms and demonstrate the improved EE UAV relaying communication for our model.

The integration of unmanned aerial vehicles (UAVs) into spectrum sensing cognitive communication networks can offer many benefits for massive connectivity services in 5G communications and beyond; hence, this work analyses the performance of non-orthogonal multiple access-based cognitive UAV-assisted ultra-reliable and low-latency communications (URLLCs) and massive machine-type communication (mMTC) services. An mMTC service requires better energy efficiency and connection probability, whereas a URLLC service requires minimising the latency. In particular, a cognitive UAV operates as an aerial secondary transmitter to a ground base station by sharing the unlicensed wireless spectrum. To address these issues, we derive the analytical expressions of throughput, energy efficiency, and latency for mMTC/URLLC-UAV device. We also formulate an optimisation problem of energy efficiency maximisation to satisfy the needs of URLLC latency and mMTC throughput and solve it using the Lagrangian method and the Karush–Kuhn–Tucker conditions. The algorithm is presented by jointly optimising the transmission powers of the mMTC and URLLC users. The derived expressions and algorithm are then used to evaluate the performance of the proposed system model. The numerical results show that the proposed algorithm improves the energy efficiency and satisfies the latency requirement of the mMTC/URLLC-UAV device.

The increasing demand for higher data rates pushes the boundaries of the currently used radio spectrum. The terahertz (THz) frequency band (0.1-10 THz) is widely considered by scientific community to address spectrum scarcity. In this paper we developed a theoretical model for device-to-device (D2D) communication operating in THz band. We also derived a close form formula of data rates, outage probability, and energy efficiency. Our simulation results show an improvement of data rates and energy efficiency while decreasing the outage probability of D2D communication in THz. For instance, there is 86% of increase in energy efficiency when the transmission power is 19dBm. Finally, the improvement of energy efficiency is 87% using optimal transmission power due to 50 resource blocks.

Unmanned aerial vehicle (UAV) is a promising technology to serve as a mission-critical communication, where human operation or intervention is risky, dangerous, impossible or critical in terms of time and cost. The performance of the UAV depends highly on the operating radio environment e.g. multipath shadowing and fading, and spectrum availability. Therefore, a cognitive radio-based UAV is considered to utilize the radio spectrum opportunistically, and minimize the network congestion during a disaster on preallocated channel or degradation of the quality of service. In this paper, we have presented an analytical model for cognitive UAV downlink communication between the UAV and the ground nodes. This model aims to maximize the throughput and improve the energy efficiency by minimizing the power consumption for the UAVs. Specifically, we developed two optimization approaches to address the energy efficiency with and without the throughput of the user as constraints. Simulation results for the energy efficiency without constraints show that \(11.16\%\) and \(6.43\%\) performance improvement can be achieved for throughput, and energy efficiency respectively in comparison to unoptimized one. Similar behavior has observed with the energy efficiency with constraints and a significant improvement has achieved in throughput performance e.g. \(64.02\%\) with the cost of energy.

A medical condition is considered an “emergency” when there are limited time and resource to handle the situation. It can occur anytime or anywhere regardless of the patient’s age or gender. Sometimes it is seen that an elderly person moves on their own and they can get sick inadvertently. To mitigate the emergency medical problem without any delay, a system named i-medical is proposed in this chapter. Moreover, with a combination of different methodologies like the Internet of Things, database and mobile application, this system would help the patients immediately. Justifiably, using stochastic geometry theory, this chapter demonstrates the result of how this system would work on real-world cellular networks. Likewise, the simulation results show that better performance can be obtained by minimizing user densities such as patients and neighbors.

There is a compelling need to address the problem of accommodating the rapidly growing number of machine type devices engaging in communication within the scarce radio spectrum, in current and forthcoming generations of wireless networks. The coming decades will also witness various novel applications, demanding wireless communication at very high data rate and energy efficiency, which currently favored technologies and techniques are inadequate to support. Because of these reasons, it seems inevitable that wireless communication will have to be facilitated by the efficient utilization of larger bandwidth at higher frequencies. Non-Orthogonal Multiple Access (NOMA) and shifting to higher frequency ranges such as the lower terahertz band, have been considered as solutions to provide space to the increasing number of communicating devices while meeting performance requirements. In this paper a machine type communication system model, utilizing the promising technique NOMA and operating in the sub-terahertz band, is developed and analyzed for its performances of data rate, spectral efficiency and energy efficiency. Thereafter the energy efficiency of the proposed model is optimized by using unconstrained optimization and then constrained (by threshold of data rate) optimization, the latter solving a multi-objective problem by the ϵ-constraint method. The optimal transmission power is also derived for both optimization techniques. Finally, simulation results demonstrate that the energy efficiency can be maximized by utilizing unconstrained optimization and the spectral efficiency can be maximized by utilizing constrained optimization for both machine-to-machine and base-to-machine communications.

Motivated by the current demand for improvements in transmission rate and energy efficiency of random wireless cellular networks, we investigate the theoretical model of random cognitive radio network in Rayleigh-lognormal fading environment. In such a network, we derive an analytical expression for the connection probability, transmission rate, and energy efficiency of a secondary network in a single-tier downlink scenario, considering the probabilities of unoccupied channel selection and of successful transmission, where source-destination pairs are randomly located according to Poisson point processes. Moreover, we approach the problem of optimization of transmission rate and energy efficiency using a required connection probability constraint to improve the system performance. Our numerical results indicate that there exists an optimal combination of transmission power and secondary transmitter density where transmission rate and energy efficiency are maximized.

Wireless sensor networks (WSN) comprises of many locally distributed sensor nodes in human body which monitor physical data such as body temperature, pressure, and heart rate. The use of sensor nodes for medical health has greatly attracted the attention of researchers recently because sensor nodes can be used to monitor patient’s health condition or assist physicians in critical situations. This can greatly improve the existing patient care in health service. In this paper, Simulink model of health monitor using WSN has been designed. Parameters such as systolic blood pressure, heart rate, and body temperature have used to build the model and show the performance characteristics of various channels, i.e., AWGN, Rayleigh fading. The result shows that body temperature has the best performance in AWGN channel and heart rate has the best performance in Rayleigh fading channel.

One of the key revolutionary services that will be offered by 5G is ultra-reliable low latency communication. This will enable the development of new emerging technologies such as remote surgery and autonomous vehicles. In this paper, we have investigated the differences between Shannon theory and Finite Blocklength Information theory and evaluated their performance in various scenarios such as orthogonal multiple access, nonorthogonal multiple access, millimeter wave and beamforming. In each and every case, the Shannon model has emerged to be the better performer compared to the Finite Blocklength Information model. However, on the other hand due to two factors the result of our study was inconclusive for the Shannon model. One of these factors happen to be the probability of decoding error and the other one is Blocklength size. Our paper provides numerous results for various factors and highlights the superiority of the Shannon model over the Finite Blocklength Information model.

This paper presents the comparative cost analysis of different renewable energy sources along with traditional diesel generator for base transceiver stations. Base transceiver stations are the equipment in the cellular system which need to run 24/7 without being disturbed by any sort power outages. It is found that all the operators in Bangladesh use diesel generators during power outage. The target is to compare the feasibility of using alternative power sources to minimize the cost of the system, minimizing carbon emission and reducing the dependency on the fossil fuel. In this paper, the previous and recent data of diesel, solar and fuel cell power sources are analyzed. Finally, a new model is proposed to combine the sources with backup of diesel generator which can minimize the cost and fulfill the target.

The combination of internet of things (IoT) with environmental sensing and image processing device has opened a new era to monitor the health of plants. Classification of plant diseases in early stages using image processing and analyzing environmental sensing data not only helps farmers to get healthy plants but also maximize the production. To monitor and classify plant diseases IoT is essential to send images and give feedback on it. In this paper, a raspberry pi based IoT device is proposed which sends images of plants to classify diseases and updates environmental parameters like air temperature, humidity, soil moisture and pH in MySQL database in real-time. To segment the affected part of plant, k-mean cluster algorithm is used after performing preprocessing stage and converting into L*a*b color space. Multi-class support vector machine (SVM) is applied to categorize disease using fourteen types of features of color, texture and shape obtained when implementing gray level co-occurrence matrix where the system was able to classify with an accuracy of 97.33%. Thus, classifying diseases and analyzing environment parameters help farms to monitor plant growth efficiently for better production.

In cognitive radio networks, security issues arise when intelligent malicious users can attack and decrease the permitted channel for unlicensed users (secondary users). In this paper, we propose a novel scheme, based on friend or foe (FoF) detection technique with physical layer network coding, to enable discrimination between secondary users and intelligent malicious users. Theoretical expressions are derived for probabilities of detection of secondary user, miss detection, and false alarm. In addition, the effectiveness of the proposed approach is evaluated by theoretical analysis and Monte Carlo simulation. Furthermore, an algorithm is proposed for distinguishing between secondary user and intelligent malicious user. Finally, based on the outcome of simulation of probabilities and normalised cross-correlation, it is determined that the proposed scheme outperforms in terms of orthogonal frequency-division multiplexing (OFDM) signal compared with quadrature phase-shift keying (QPSK) signal over cognitive radio network.

This article presents a traffic management system that dynamically micro-manages city traffic by keeping track of the precise number of stationary vehicles at every intersection. It can be implemented quickly at a relatively low cost. Through the use of localised computing, a trilateration system, integration of internet of things (IoT) and development of an algorithm which manages the green signal timing on a per lane basis we create a system which is not only cost effective, but also provides vehicle security and public notification of citywide traffic congestion. It is capable of working in conjunction with both human driven vehicles of today as well as the self-driving vehicles of tomorrow. We simulate overall effectiveness of the system in MATLAB for worst-case scenario and have nonetheless found favourable (5-10% improvement) results.

Presently there is a globally growing demand across all industries for small and portable electronic devices which feature Internet connectivity. This is largely due to their ease of use provided by robust interoperability and feasibility in almost any scenario. An example of such devices are the sensors used in a wireless sensor network (WSN) where prolonged battery life is a major challenge. This paper presents energy efficiency optimization techniques to reduce transmission power and further validate our findings through the use of single and double-slope modeling in MATLAB. In the simulations multiple aspects have been studied such as the connection quality, energy efficiency and optimal power with respect to distance and transmission power. The results have shown that the proposed optimization technique provides improvement to existing WSN technology (e.g. a 38.9% reduction in optimal power usage at the same pathloss distance).

Medical emergencies are such that they can occur at any moment regardless of the situation or a person's age. Often the victims of curable medical conditions are the elderly who happen to be out and about without anybody to help. To tackle this we propose Neighbor Assisted Medical Emergency System (NAMES), which through the use of Arduino and Internet of Things (IoT), initiates a cost effective emergency response. NAMES is based around having registered volunteers who provide immediate medical care to those in need on the spot or take the responsibility to escalate the situation towards a hospital or a registered pharmacy for equipment when necessary. Furthermore we introduce a simulation model of NAMES in MATLAB based on experiment results to analyze the system performance using the theory of stochastic geometry. Performance evaluation in terms of outage probability reveals the effects of NAMES system on propagation environment. Our proposed system will incorporate loT, mobile network, database etc to form a response system in case of emergency medical situation in Bangladesh.
