Multipath Extension of AODV to Improve End to End Delay
This paper describes improvement in standard routing protocol AODV for mobile ad-hoc networks. The authors' mechanism setups multiple paths based on less hop count. It allows to store multiple paths based on threshold. At time of link failure, it will switch to next available path. To set up multiple path, they have used the information that they get in the RREQ packet and also send RREP packet to more than one paths. 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. The main features of their mechanism is that it is simple, efficient.
