Uma Abordagem Baseada em QoS para Seleção de Nós Ativos em Redes de Sensores sem Fio

Flávia DelicatoFabio ProttiJosé Ferreira de RezendeLuci Pirmez

We propose a strategy for node selection in wireless sensor networks that prioritizes nodes with larger residual energy and relevance for the application. The proposed scheme is based on an implementation of the knapsack algorithm and it seeks to maximize the network lifetime while assuring the application QoS. An environmental monitoring application was simulated and significant energy savings were achieved with the proposal.
