DPCS: A distributed power control scheme for mobile wireless sensor networks

Abstract

Wireless sensor networks provide a lot of interesting to monitoring applications. However, the problem of limited energy of sensor disrupts the proper functioning of the network by limiting its lifetime. In fact, the aspect of minimize energy consumption and maximize lifetime of sensor networks is constituted a real challenge. In this paper, we propose a novel distributed power control scheme (DPCS) for mobile wireless sensor networks. The main idea behind the proposed scheme is developing an effective mechanism for manage the transmission power when nodes are mobile. DPCS aims to reduce the energy spent at communication and at the time ensuring a good connectivity. Simulations show that our scheme realizes an improvement compared to the classic scheme, in terms of network lifetime and connectivity in spite of the sensors mobility.
