Enhancement in network lifetime and minimization of target coverage problem in WSN

Enhancing network lifetime in wireless sensor network is related with target coverage problem while continuously monitoring a set of targets. Target coverage problem is nothing but each target should be in the coverage range of at least one sensor node. A sensor cover is a set of sensors that covers all the targets. Target coverage is achieved by proper deployment of sensor nodes and network lifetime is increases by scheduling activities of cover sets. So in this paper, performance of heuristic and artificial bee colony deployment algorithms are compared on the basis of upper bound of network lifetime. Then two scheduling techniques, heuristic and ant colony are analyzed for providing calculated upper bound for particular deployment technique. This analysis will help to improve the performance parameters of wireless sensor network.
