Energy Balancing Multi-path Routing for Wireless Sensor Networks

This article presents a new flooding routing protocol for wireless sensor networks based on a Location-Aided data dissemination scheme. This protocol uses node´s information to select proper routing path in virtual grids, thereby balancing energy consumption to better prolong the life-time of the whole network. Multiple paths from internal nodes to gateway nodes are established as much as possible, and energy factors are introduced for all nodes. The proposed approach achieves balancing energy consumption by selecting one path whose reserved residual energy is more than others´ by selection rules. Through analysis from simulation results, the improved protocol can preserve longer life-time than prior methods.
