Equal energy dissipation in wireless sensor network

摘要
En 中文
Wireless sensor network consists of a large number of energy constrained nodes. The lifetime of such a network is limited by the energy dissipated by individual nodes. The important issues are of modeling a sensor network and assessment of its lifetime. This paper gives an analytical framework to establish equal energy dissipation over a network. The equal energy dissipation profile is first obtained for a linear array of wireless sensor nodes and then it is extended for a Y-shaped array of nodes in order to cover a planar area. This approach ensures that all nodes run out of battery energy almost simultaneously. It is shown that the network lifetime almost doubles with the proposed scheme as compared to other reported schemes. (C) 2016 Elsevier GmbH. All rights reserved.
