Problem statement: In this study, we proposed a method to improve the performance of AODV by reducing overhead by adopting a route message propagation mechanism. According to the new scheme, a node will be selected to forward a routing request message if and only if a condition based on its mobility (speed) and number of neighbors is satisfied. If the routing request is allowed to propagate through a node then there will be at least a possible path which includes that node in its path list. So, at the end of the route resolving process, the destination will have a possible path through that node. If the routing request is disallowed to propagate through a node then there will not be a possible path which includes that node in its path list. So, at the end of the route resolving process, the destination will not have a possible path through that node. We implemented the idea on network simulator (ns2) and measured the improvement in performance. Mobility and node density are the two major factors which has much influence on the performance of any routing protocol of mobile adhoc network. Several previous works highlighted this fact. In this study, we will improve the performance of AODV by adding mobility and density aware behaviors in route resolving process. Approach: In this study we describe an idea for improving the performance of AODV and reduce some of the overheads in a large and dense network with mobile nodes with different speeds. The proposed design will be implemented on AODV as an extension and will give a new protocol namely Mobility and Density Based Extended AODV (MADA-AODV). Results: The performance of MADA-AODV has been compared with the other routing protocols AODV,DSDV and DSR with metrics throughput, MAC load, Routing Load, Control message overhead will be used to measure the performance of the protocol in terms of different network overhead. We have arrived more significant and comparable results. Conclusion: We have successfully implemented the proposed protocol MADA-AODV and compared it with other routing protocols AODV, DSDV, DSR. We evaluated the performance of these protocols in terms of different metrics. In almost all the cases, the performance of MADA-AODV is better than normal AODV as well as other compared routing protocols. Significant improvement in throughput as well as significant reduction in overhead is provided by MADA-AODV. So we hereby conclude that MADAAODV will be suitable for highly mobile and dense network scenario
