This flexibility gives rise to new applications of networks which were not possible with the networks that critically depend on an infrastructure for their operation. However this absence of infrastructure also gives rise to a host of problems with the network operation. Routing data from a source to destination is one such problem. Mobility of the nodes causes frequent topological changes and further complicates the problem. Many protocols have been proposed to help route data in mobile ad hoc networks. A sub class of these protocols makes use of a set of multipath routes to transmit data from the source to the destination. During the course of our research we discovered inefficiencies associated with these routing protocols. We have proposed the reuse of cached routes as a technique to reduce these inefficiencies and improve the performance of mobile ad hoc network along various performance parameters. We have proposed a new multipath routing protocol called CMR that makes use of the technique of reusing cached routes in determining new routes. Through extensive simulation experiments we have been able to analyze the performance of new protocol and demonstrate its advantages.
