- Abstract
- Many routing protocols have been proposed for sensor networks where energy awareness and reliability are essential design issues. This paper proposes an energy-aware data gathering method called Energy-aware Tree Routing (ETR) in Wireless Sensor Networks. The proposed scheme relates to reliable and energy efficient data routing by selecting a data transmission path in consideration of residual energy at each node to disperse energy consumption across the networks and reliably transmit the data through a detour path when there is link or node failure. Simulation results show that the proposed method outperformed traditional Tree Routing (TR) by 23%-55% in network lifetime. ©2009 IEEE.
