Routing protocol for ad hoc mobile networks using mobility prediction

Over the lasts years there has been a growing interest on Mobile Ad Hoc Networks (MANET), in this network nodes are carried by people and connected to each other by multi-hop wireless links. Since the nodes can move freely, then the node mobility pattern became an important characteristic of the MANET. A large number of network tasks are influenced by mobility. Mobility introduces uncertainty in future nodes positions and consequently in the network topology as well. In this work we propose a novel prediction method to forecast the future node position. The method was derived using pedestrian tracked data. This method provides a future position estimation with reasonable low error. Using this method we propose a novel geographical routing protocol that uses the predicted position in the routing decision process. The method prediction performance is contrasted against a real trajectory and the routing protocol performance is tested in computer simulations against others existing geographical routing protocols.
