With mobile data growth and rapid urbanization trends, there will be an extremely high density of wireless communication links in cities, therefore users expect an environment where they can access the Internet to their devices anytime, anywhere. Due to CAPEX/OPEX problems, a small cell deployment is not an economical strategy in scenarios of intense data tra_c, so the use of UAVs to improve network coverage and performance becomes feasible. In order to improve the Quality of Service of the network, a computational system was proposed to perform decision making that receives as input network information such as network throughput, packet loss rate and delay, and returns to network quality for that speci_c type of network. application. The system as a whole veri_es the necessity or not of using Unmanned Aerial Vehicles (UAVs) to improve the quality of the network and the coverage of the area of greatest demand. If UAVs are required, they are shifted to the areas of greatest demand. Otherwise, the UAVs remain in the base station. Through the proposed method there were signi_cant improvements in the Quality of Service (QoS) of the network, allowing a reduction in packet loss and delay, and an increase in the network throughput rate.

Iluminação pública com medição ponto a ponto e gerenciamento remoro: uma evolução tecnológica smart
(Universidade Federal do Pará, 2022-02-26) RAMOS, Ricardo Guedes Accioly; TOSTES, Maria Emília de Lima; http://lattes.cnpq.br/4197618044519148
The concept of smart city, refers to the availability of technology for sustainable development, respect for the environment and improving the quality of life. For the implementation of a technology with such scope, you can do use of a structure existing public lighting, transforming a system used for night lighting, on a platform dynamic, providing a connection with other systems, offering services such as public safety, pollution sound, air quality, among others. This work proposes, a technology of low cost and losses, presenting as objective, the development of a prototype of a data acquisition system for point-to-point measurement, contemplating the communication with a general management system of municipal Public Lighting for the monitoring, reduction of costs with operation and maintenance, contributing to a possible discussion of the decrease in the value of the Contribution to the Cost of Public Lighting (COSIP). It is technology he can change the COSIP billing, which is calculated based on estimation of energy consumption of Public Lighting, being able to generate economy to the consumer. the search specifies the prototype capable of measuring _ parameters electric make _ communication between the measurement module and the processor and make the information available in a Wi-Fi network, capable of being acquired by a server, which processes data and sends the command back to actions. This resource is analyzed through an experiment and the _ results are treaties to conclusions finals about the topic.
