In this article it is included the design of a smart parking system, the base was the current system "Sistema integrado de Estacionamiento (SIMERT)" and the mobility in Loja - Ecuador, with the use of a sensor network and wireless technology based in Zigbee 900 and Digimesh 2.4 GHz. To the feasibility of the project it was considered a technological platform that could be adapted to the city conditions and that be friendly with the environment, furthermore the suggested solution gives us connectivity with a Web application for integrated parking and usability of administrators and final users.

For humankind to survive, access to sufficient and safe drinking water is fundamental. This study explores the connection between rising domestic water consumption and planetary phenomena, such as rapid population growth, climate change, and pandemics. To achieve the study’s objectives, it provides a thorough forecast of water use, considering probable global scenarios for the years 2030 and 2050. The modeling approach is adapted from a consistent case study taken from the body of scientific literature on water supply hydraulics. The study’s results highlight the necessity for proactive and flexible management strategies for water resources. Notably, it observes significant alterations in water supply management to adjust water allocation due to the unanticipated and ongoing increase in consumer demand. The forecasted scenarios indicate potential difficulties that may arise in meeting rising domestic water demand amid planetary phenomena. The presented results offer valuable insights to policymakers and water supply authorities, enabling them to effectively address the rising domestic water demand while considering potential adverse conditions, ensuring a sustainable water supply for future generations.

The measurement of weather variables in the Andes Mountains of Ecuador is of great importance for environmental, hydrological and ecological research. Such investigations reveal indicators that contribute to innovative management of Territorie, which it is characterized as a biodiverse natural heritage. Due to heterogeneity of the distribution of rainfall and other weather variables in in that region suggest the need to use radar systems LAWR (Local Area Weather Radar), to mapping of variables with high temporal and spatial resolution. However, the outputs of these radar systems are required to calibrate in real-time with ground nodes measurements. Therefore, the radar system LAWR, available in the province of Loja-Ecuador intended for research between the University (UTPL) and the autonomous governments (GADs), needs to be complemented with real-time monitoring of variables acquired by the reference weather stations located in the study area. Based on the above, the objective of this work is to design, implement and evaluate a remote real-time monitoring system of weather variables acquired by measuring ground stations based on Davis Vantage Pro. The implemented system is based on GPRS and provides reliable (max. error 1.5%) and timely (every 5 min.) information to enable to researchers intelligent management of territories.

The current trend is to connect everything to network to be monitored and controlled remotely through own concept IoT technologies. One of the problems is to connect the devices to a network, using technologies with sufficient coverage and capacity, so this article shows the development of a mobile gateway for IoT applications under the Android platform evaluated in 4G mobile networks. The IoT mobile gateway sends the data collected from sensors by selecting the MQTT and HTTP protocols, to IoT platforms on the Internet. The architecture is composed of temperature, luminosity and pressure sensors that are integrated into a sensor node which function is for data collection, processing and then via Bluetooth is sent to an Android smartphone where an application that performs the mobile gateway function is running, here data network are sent through the 4G LTE network to the IoT platforms of Ubidots and Watson IoT. Subsequently, tests were carried out with various metrics such as latency, energy consumption and connection costs. It concludes that IoT mobile gateway has better performance under MQTT protocol compared to HTTP.
