This paper describes improvement in standard routing protocol AODV for mobile ad-hoc networks. The mechanism setups multiple optimal paths based on bandwidth and delay. It allows to store multiple optimal paths based on Bandwidth and delay. At time of link failure, it will switch to next available path. To set up multiple paths, the authors have used the information that they get in the RREQ packet and also send RREP packet to more than one path. It reduces overhead of local route discovery at the time of link failure and because of this end to end delay and drop ratio decreases.
