AODV with Route Backup List routing algorithm for Mobile Ad hoc Networks

: A mobile ad hoc network is a multi hop wireless network created by a group of mobile nodes that have wireless potential Connections in MANET (Mobile Ad hoc Networks) are recognized and withdraw dynamically as the network is dynamic. The mobile nodes in the network can connect and go away the network anytime. Communication of information becomes neither challenging in such networks where the position of a node is neither fixed nor the link joining the two nodes permanent. Efficient protocol are required for uninterrupted transmission of data in the network. Research in the field of designing a better algorithm is an upcoming area, the probable result of which is an efficient algorithm which can facilitate better performance. This work offer improved AODV (Ad hoc On demand Distance Vector) routing algorithm named as AODVRBL which helps in fast rebuilding of the broken links from source to target. Algorithm maintains a backup list at the source node containing all the possible routes from source to target. The model has been executed and tested on Network Simulator and results and graph are compared with classical AODV protocol. Results show the better presentation of the proposed protocol.Key terms: AODV, AODVRBL, MANET, Throughput, PDR, RREQ, RRER, RREP.
