Load-Balance Directed Diffusion in Wireless Sensor Networks
Wei Kuang Lai, Yuh-Chung Lin, Tsung-Han Chen, Chin‐Shiuh Shieh · 2011
How to reduce the sensor node power consumption in wireless sensor networks is one of the important research issues. Many routing protocols based on the directed diffusion have been proposed to improve the network performance. Most of them calculate the gradient relied on power-related information and hop count, but do not maintain the selected path. In this paper, we propose a new path switching mechanism which automatically switches on the routes based on the known gradient information to achieve load balance.
