Due to the inevitable existance of location errors in WSN with localization, there is the need to study the impact of errors on geographic routing. In this paper, we focus on some of the fundamental issues caused by location errors in the design of energy-efficient geographic routing algorithms in WSNs. The results of our analysis show the clear need of an energy-efficient geographic routing protocol...
Existing power efficient geographic routing algorithms have been shown to be able to reduce power consumption and hence prolong the lifetime of multi-hop wireless networks. However, in practical deployment scenarios where location errors inevitably exist, these algorithms are vulnerable to a substantial performance degradation in terms of energy consumption. Since location errors always exist no matter...
