1. Energy Efficient Clustering in Multi-hop Wireless Sensor Networks Using Differential Evolutionary MOPSO
ABSTRACT The primary challenge in organizing sensor networks is energy efficacy. This requisite for energy efficacy is because sensor nodes capacities are limited and replacing them is not viable. This restriction further decreases network lifetime. Node lifetime varies depending on the requisites expected of its battery. Hence, primary element in constructi

2. Modelo distribuído para agregação de armazenamento em redes de sensores sem fio=Distributed model for storage aggregation in wireless sensor networks / Distributed model for storage aggregation in wireless sensor networks
Storage management of Wireless Sensor Networks (WSN) is a very critical issue in terms of system s lifetime. While WSNs host a vast storage capacity on the aggregate, that capacity cannot be used entirely. Eventually, the entire network may fail when the first sensor has its own storage capacity depleted, leaving behind a large amount of unutilized storage c

3. Gerenciamento AutonÃmico de Energia em Redes de Sensores Sem Fio AtravÃs do Escalonamento de Atividade dos NÃs / Autonomic Management of Energy in Wireless Sensor Networks Through the Node Activity Scheduling.
A evoluÃÃo no desenvolvimento de novos dispositivos, cada vez mais baratos e eficientes, expandiu o uso das Redes Sensores Sem Fio (RSSF) e incentivou a criaÃÃo de novas aplicaÃÃes, no cenÃrio contemporÃneo da ComputaÃÃo UbÃqua e Pervasiva. No entanto, a limitaÃÃo de energia continua sendo um desafio na Ãrea de RSSF. Essa situaÃÃo à agravada

4. Uma abordagem para minimização de consumo de energia em redes de sensores sem fio com sorvedouros móveis
In this work, we introduce a new network topology model and algorithms to minimize the energy consumption in Wireless Sensor Networks (WSNs) with mobile sinks. On the one hand, the proposed optimization problem explicitly minimizes the energy consumption rates due to message forwarding. On the other hand, it also attempts to keep message delay rates at low l

5. Algoritmo para o problema de atribuição de papéis em redes de sensores sem fio
Recent technological advances allowed the combination of embedded systems and wireless communication, making possible a new type of mobile ad-hoc network, known as Wireless Sensor Network (WSN). These networks have the capacity to monitor the physical world through small sensors that operate in integrated and collaborative way. Due to the compact nature of t

6. Um protocolo de roteamento para redes sem fio adaptável por regras de aplicação
The exchange of information among the layers of the communication stack has been frequently used in Wireless Sensor Networks (WSNs) to increase the performance of the network. Such interaction among layers enhances the reliability and eciency of the communication, despite the severely restricted resources found on sensor nodes. However, such optimizations im
