A routing protocol with mobility prediction and multi-path routing in Ad Hoc Networks

The topology of ad Hoc network is always dynamic and there are usually multiple routing paths between source nodes and destination nodes. So the routing protocol in ad Hoc networks should adapt to the dynamic topology and take advantage of the multiple paths. This paper provides a protocol PMDSR based on DSR, which makes use of the algorithm of mobility prediction and multi-path routing. It can acquire the information such as the position, velocity and moving direction of the moving nodes via GPS to predict the lifetime of the link between the adjacent nodes and choose multiple steady routes to delivery packets. The simulation results show that PMDSR increases the average delivery rate and decreases the average delay.
