Energy aware linear sensor placement scheme for water pipeline monitoring

摘要

Wireless sensor networks (WSNs) have been widely deployed in many areas. Water pipeline monitoring is among the areas where WSNs have a great effect on their supervision. However, it is critical to control the power consumption of the sensor nodes to achieve the maximum WSNs' operation time. In this paper, we study the linear sensor placement problem in order to maximize the lifetime of sensor nodes used to monitor water pipelines. An efficient equal-distance placement scheme is proposed. The evaluation results using Mathworks Matlab show that our energy aware linear sensor placement scheme improves the WSN's lifetime. The effect of scaling the number of nodes on the transmission power is also tested in this paper.
