A Modified Approach for Route Maintenance Using Alternate Path in AODV
Rakesh Kumar, K. V. Arya · 2011
AODV is an on demand routing network protocol which is specially design for ad hoc networks. This protocol starts to establish the route, only when a certain node claims to send data and is an efficient ad hoc network routing protocol for data transfer. AODV suffers from the limitation of low bandwidth. In the AODV routing protocol, wherever a link breaks an error message is sent to the source indicating the link failure and further communication is stopped temporarily. This paper proposes an improved AODV routing protocol by including route repair scheme to overcome the link failure problem s of its predecessor. In the proposed scheme the data packet is sent through alternate routes instead of dropping it. It is shown through simulation results that the proposed scheme is robust for data delivery.
