AD-AODV: A Improved Routing Protocol Based on Network Mobility and Route Hops

In order to alleviate the node mobility problem which cause frequent link ruptures between source and destination nodes and data packets loss during transmission in Mobile Ad hoc Networks, we propose a new routing protocol called AD-AODV based on the famous AODV protocol. By introducing a novel metric M whose value depends on the hop number and average mobility of a given route, we improve the routing mechanism of AODV and enable AD-AODV to select the most stable route.A lot of simulations are operated based on the variation of node number and node speed to evaluate the performance of AD-AODV protocol. Simulation results compared with AODV protocol indicate our protocol's superiority in terms of packet delivery ratio therefore AD-AODV's enhancement of routing reliability is proved.
