Recent research results show that a wireless ad hoc network can exploit controlled node mobility to reduce communication energy consumption. Node movement, however, may consume a ...
The problem of optimal data gathering in wireless sensor networks (WSNs) is addressed by means of optimization techniques. The goal of this work is to lay the foundations to devel...
—Recharging the batteries of a moribund sensor deployed as part of a wireless sensor network is often infeasible due to logistical considerations. With the purpose of prolonging ...
Abstract: This paper addresses the target coverage problem in wireless sensor networks. Communication and sensing consume energy, therefore efficient power management can extend ne...
—One approach to prolong the lifetime of a wireless sensor network (WSN) is to deploy some relay nodes to communicate with the sensor nodes, other relay nodes, and the base stati...
