Abstract

Power consumption is a fundamental concern in wireless multimedia sensor networks (WMSNs). Node placement scheme in WMSNs has considerable impact on network lifetime. In this paper, we investigate and develop an power-efficient node placement scheme (PENPS) in linear wireless multimedia sensor networks, which can minimize the average energy consumption per node and maximize the network lifetime. The analysis of PENPS and the comparison of performance with the equal-spaced placement scheme (EPS) show that PENPS scheme can significantly decrease the average energy consumption per node, which can prolong the lifetime of sensor nodes and sensor networks effectively.
