— To achieve power-efficient monitoring of targets in a terrain covered by a sensor network, it is sensible to divide the sensors into cover sets and make each of these sets responsible for covering the targets for a certain period of time. Generating the maximum number of such cover sets, has been proved to be an NP-complete problem, and thus algorithms(More)
—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)
