Energy Aware Routing Algorithm for Target Region Monitoring in Wireless Sensor Network

摘要：

In this paper, we propose a novel energy aware routing algorithm for target region monitoring in wireless sensor network. In our algorithm, a gathering node is chosen within target region based on energy metric and hops to sink to gather and aggregate data. Multiple paths are found between gathering node and sink, and each path is assigned a probability of being chosen, depending on the energy metric and communication cost. Our routing algorithm uses sub-optimal paths occasionally besides the minimum energy path from the gathering node to sink. The simulation results show that the proposed algorithm saves energy consumption, decreases transmission delay compared with current schemes like directed diffusion algorithm.
