Dead reckoning in mobile ad hoc networks

A predictive model-based mobility tracking method, called dead reckoning, is proposed for mobile ad hoc networks. It disseminates both location and movement models of mobile nodes in the network so that every node is able to predict or track the movement of every other node with a very low overhead. This technique is applied to solve the unicast routing problem by modeling link costs using both link lifetime and geographic distance from the destination to the link egress point. This method presents a much superior routing performance compared to either DSR or AODV, two other popular routing protocols, particularly in terms of delivery fraction and routing load.
