Abstract: There are many reactive algorithms in use for mobile ad-hoc networks. The protocol we have taken into consideration is the multi-path dynamic MANET on-demand protocol. It uses ‘Flooding Technique’ for route discovery and special routing packets to accomplish its functionalities. A route request packet is used to discover all the available paths from the start point to the end point. A route reply message is sent which backtracks through the path in which route request arrived. Whenever the path from the starting place to the end breaks, the error is notified by means of RERR packets. The need for discovering multiple paths is that even when there is a break in one path, we make use of an alternative path to route the packets to the destination. The difficulty we are facing with the MDYMO protocol is that whenever a request from a node arrives, it floods packets to the entire network, thereby causing a broadcast overhead. In this study, we overcome the problem by coupling the Neighborhood Discovery Protocol (NHDP) along with MDYMO protocol. The NHDP protocol discovers and periodically updates information about its 1 and 2-hop neighbors, maintains them in its cache and uses it when a request arrives, thereby reducing the broadcast overhead.
