In MANET whenever there is a need to send data packet from a source s to destination d, a route is discovered from s-d which usually consists of a shortest path. But use of such shortest path leads to congestion at the intermediate nodes causing a lot of packet drops. One solution to overcome this problem is load balancing. There are several techniques of load balancing proposed in Mobile Ad Hoc Networks. The methods are mainly based on finding multipath between a pair of source and destination nodes and finally splitting the traffic across the paths. The major issues of conventional multipath routings i.e. node, and link disjoint routings are that they present a lot of control overhead and are not really power saving due to lot of interference in the physical layer. Since nodes communicate through the shared wireless medium, the selected paths need to be as independent as possible in order to avoid transmissions from a node along one path interfering with transmissions on a different path. In this paper we propose a modified version of Adhoc On-Demand Distance Vector Multipath (AODVM) protocol called “Neighbor Non-correlated Multipath Routing” protocol. The main goal of “Neighbor Non-correlated Multipath Routing” is to reduce the interference among the constituent multipath which not only minimizes the control packets overhead but also ensures that the packet losses due to interferences are minimum. The technique is further compared with the other multipath routing techniques such as node and link disjoint multipath and the results are presented.
