Predictive Mobility-Based and Location-Aware Routing Protocol in Mobile Ad Hoc Networks
E 計劃編號 NSC · 2004
Recent years, many location-aware routing protocols have been proposed for the mobile ad hoc networks. The routing performance is improved by exploiting the position information of the mobile nodes. However, the mobility characteristics of the mobile nodes have not been taken into consideration. An external location service for updating the position information of the mobile nodes is assumed as a requirement in most of the related work. In this paper, the proposed Predictive Mobility and Location-Aware Routing (PMLAR) algorithm incorporates the mobility behaviors of the mobile nodes in the protocol design. The region for packet forwarding is determined by predicting the future trajectory of the destination node. By adapting the prediction mechanism, proposed protocol provides efficient routing performance without the assistance of external location services. Simulation results show that the proposed PMLAR algorithm out performs other routing protocols under different network topologies.
