摘要: Abstract Wireless charging brings forward several new challenges in designing energy efficient wireless sensor networks. In a scenario, number of chargers with high resources are placed the network to recharge power constrained nodes. Nevertheless, due fading effect signals, few only nodes can remarkably benefit from charger emission. For this reason we examine whether organization clusters may extend lifetime. paper, compute maximum size cluster and propose an localized algorithm as well centralized one position so maximize We compare other solutions literature present both theoretical simulation results show effectiveness our approach. The up 360% increase lifetime comparison traditional 1-hop communication method between sink.
