Location-Aided Multipath Routing Method for Mobile Ad Hoc Wireless Networks
Ha Duyen Trung, Watit Benjapolakul · 2006
In mobile ad hoc network (MANET), there are a number of routing schemes that have been proposed and several of these have been already extensively simulated or implemented as well. In this paper, we describe extension to routing algorithm based on location information to provide more efficient routing for mobile ad hoc networks. We propose replacing location-aided routing (LAR) with location-aided multipath routing (LAMR). We implemented LAMR through simulation using ns-2 and study its efficiency, and other properties. We use random waypoint mobility and compare LAMR approach versus ad hoc on-demand distant vector (AODV), ad hoc on-demand multipath distant vector (AOMDV) and LAR methods. Our simulation results demonstrate the performance benefits of LAMR over LAR and AODV in most movement scenarios. AOMDV does more frequent flooding of control packets and thus requires higher bandwidth usage than LAMR.
