Abstract

A critical aspect of applications in wireless sensor network is network lifetime. Wireless sensor network are usable as long as they can communicate sensed data to processed node. Sensing and commu nication are important activities and they consume energy. So power management and sensor scheduling can effectively increase the networks lifetime. There are many issues that can be considered for energy efficient target coverage. For example t he coverage objective, i.e. maximize the lifetime of the network or minimize the required number of deployed sensors, the node deployment method, which may be random or deterministic, the homogeneous or heterogeneous nature of the nodes, i.e. whether all nodes have a common sensing or communication range ,the degree of centralization, i.e. .centralized vs. distributed algorithms, cover set independence, i.e. whether a node appears in exactly one of the generated sets (node - disjoint coverage algorithms) or not (non - dis joint coverage algorithms). In this paper we have presented an overview of WSN and some strategies of energy efficient target coverage in WSN.
