Analysis and Enhancement of Multipath Routing in MANET  
  Authors : Namrata Chavan; Shilpa Verma

 

Mobile ad hoc networks are vulnerable concerning link breaks, since the nodes are mobile and moving consistently. Many routing protocols for MANET are already tested in different simulators. Single path routing is used to find out single path from source to destination. In case of link breakage it drops that packet since no alternate path is available from source to destination until new path is discovered. Multipath protocols which allow more than only one path for routings; the incentive of multipath routings is evidently to reduce the overhead and to guarantee a better network load balancing. When there are multiple routes between the source and the destination, the sending source might just skip to the second route when the first one is broken without restarting a new route discovery process which is time intensive. In this paper we compared and analyzed proposed contention based multipath algorithm with modified version of AODV (AODV Multipath) that allows multiple node disjoint path from source to destination.

This paper evaluated the performance of proposed multipath routing algorithm with AODV Multipath protocol. Proposed mechanism limit the power consumption of mobile nodes to some extent and it provides better performance compared to AODVM protocol. Contention window selects path with less contending nodes from source to sink so reduces overhead in network. Along with this use of multipath routing improves the efficiency of network. Contention window based multipath routing algorithm is analyzed with different parameters. Results will be obtained as Contention window based multipath routing algorithm providing better performance compared to AODVM.
