— A key challenge in ad-hoc, data-gathering wireless sensor networks is achieving a lifetime of several years using nodes that carry merely hundreds of joules of stored energy. I...
Investigating realistic simulations in wireless sensor networks has been an area which has drawn a lot of research interest. These simulations are used to predict the lifetime of ...
—The paper addresses the maximal lifetime problem in sensor-target surveillance networks. Given a set of sensors and targets in an Euclidean plane, each sensor can watch all targ...

Wireless sensor networks (WSNs) are known to be highly energy-constrained and each network’s lifetime has a strong dependence on the nodes’ battery capacity. As such, the netw...
