Abstract
A Mobile Ad-Hoc Networks (MANET) is a collection of mobile nodes that can communicate with each other using multi-hop wireless links without utilizing any fixed base-station infrastructure and centralized management. Each mobile node in the network acts as both a host generating ows or being the destination of flows and a router forwarding flows directed to other nodes. Selecting a long route that satisfy the quality of service criteria in MANET is very critical task. In this paper we propose a new Backup and Stable path Adhoc on Demand Multipath Distance Vector (BSAOMDV) routing which is an enhancement of adhoc on demand multipath distance vector routing (AOMDV) protocol. It design in such a way so that it selects the long lasting, and delay sensitive path for data communication. In BSAOMDV we also modified the protocol in such a way so that it generates the destination of the source node when the number of alternate path becomes zero. This protocol is compared with the Adhoc on demand multipath distance vector routing protocol. We use ns2 simulator for simulation. From the simulation we obtained that our new protocol BSAOMDV outperform than AOMDV in packet delivery ratio and throughput. And also similar or better for lower mobility i.e. Mobility speed less than 15 m/s.
