Use of Street Maps to Aid Node Localization in Mobile Wireless Networks

This paper proposes a novel node localization algorithm that collaborates with street maps to estimate the locations of mobile nodes. It uses simple motion equations for moving objects in two dimensions to estimate the location of nodes, and then verifies the estimated location using street maps. This localization algorithm reduces the number of periodic beacons propagated into the network and reduces the latency or the time delay to update location information. Performance assessment was tested by simulation using MATLAB. This algorithm can be used in routing for wireless mobile and personal area networks that use geographical routing.
