Geographic routing a.k.a. location aided routing for mobile ad hoc networks is popular for being able to meet the challenging issue of scalability and efficiency in dynamic networks. In the analysis of geographic routing, it is assumed that all the nodes know their location. On the other hand, localization for WSNs is another challenging research area. As localization error can hinder geographic routing performance significantly, it is essential to have a combined evaluation of localization and geographic routing to understand the tradeoffs among different self-localization schemes for location based routing in WSNs. In this paper, several practical localization methods are evaluated for their suitability to geographic routing by extensive simulations.
