Abstract :
The power-aware geographic routing algorithms provide energy-efficient and scalable solutions for wireless sensor networks. However, to the knowledge of the authors, no previous work has analyzed the impacts of localization errors on energy consumption in the power-aware routing, and no solution for this problem has been brought forward. In this paper, the error distribution of the widely used MLE localization system is first analyzed. Then based on the knowledge of the error distribution, a robust routing algorithm is provided to mitigate the effects of the localization errors on the energy consumption. It is shown in the simulation results that our algorithm can reduce the extra energy consumption caused by the localization errors and improve the successful delivery rate
