An Energy-balanced Reliable Routing Metric for Wireless Sensor Networks

摘要

An energy balance routing metric measure based on ETX was proposed, which aimed at the limited energy and the special requirement of transmission reliability for wireless sensor network. This method improves the ETX routing metric measure. It avoids the data packet transmit along the lower energy path, and selects the path which has more surplus energy. Thus it makes the energy of the node in the network keep balance. Simulation results show that this method can prolong the lifecycle of the network and implement the effective balance of transmission reliability and energy balance.
