Vehicular ad-hoc networks (VANETs) have been gained importance for the inter-vehicle communication that supports local communication between vehicles without any expensive infrastructure and considerable configuration efforts. As many value-added or customized applications can be provided in VANETs, geographic routing has received much attention to achieve efficient end-to-end data delivery. However, how to provide light-weight and scalable location management service which facilitates

In this paper we will present a novel peer-to-peer location management protocol, called PLM, to provide location management service in VANETs. PLM makes use of high mobility in VANETs to disseminate vehicles' historical location information over the network; and then a vehicle is able to predict current location of other vehicles with Kalman filtering technique. Our theoretical analysis shows that PLM is able to achieve high location information availability with a low protocol overhead and latency. We also evaluate the performance of PLM via extensive simulations. The simulation results indicate that PLM can provide fairly accurate location information with quite low communication overhead in VANETs. The performance of geographic routing with PLM is close to that with perfect location information. Index Terms VANET, location management, peer-to-peer, Kalman filter.
