—Controlled mobility is one of the most complex challenges in Wireless Sensor Networks (WSN). Only a few routing protocols consider controlled mobility in order to extend the network lifetime. They are all designed to optimize the physical route topology from a source to a destination. However, there is often more than one sensor which reports an event to(More)
In this paper, we propose an algorithm to efficiently (re)-deploy the wireless mobile routers of a substitution network by considering the energy consumption, a fast deployment scheme and a mix of the network metric. We consider a scenario where we have two routers in a fixed network and where a robust connection must be restored between those two routers(More)
Wireless charging brings forward some new principles in designing energy efficient networks. A number of energy transmitters are placed in all over the network to recharge power constrained nodes. Since a few only nodes can remarkably benefit from the transmitter power emission, we organize the nodes in clusters and we propose an efficient localized(More)
