Mobile Ad-hoc Networks (MANETs) are described by connectivity through a collection of wireless mobile nodes along with rapid changing network topology. Wireless mobile nodes are free to move autonomous of each other, which make routing processes more complicated. In order to assist communication in the network, a routing approach is required to discover and maintain routes between wireless mobile nodes. This article suggests a new approach for MANET routing protocols, specifically for Dynamic Source Routing (DSR) protocol. We named it IRC. Basically, IRC utilizes an Improved Route Cache method for efficient route caching. It aids mobile nodes to reorder their route caches as soon as a new route has discovered. Since IRC employed two different concepts, freshness and shortness of the source route to select an efficient source route for possible future use. As results, excessive experiments show that the improved DSR (which uses IRC method) outperformance the standard DSR protocol in several simulation scenarios, specifically: the packet delivery ratio, routing overhead, and dropped packet ratio with respect to the mobility. All the simulation scenarios have been carried out with GloMoSim simulator.
