Load balancing and route stability in mobile ad hoc networks base on AODV protocol

In this paper, we propose two methods for improve the AODV protocol. A new multipath routing protocol that uses all discovered path simultaneously for transmitting data, by using this approach data packets are balanced over discovered paths and energy consumption is distributed across many nodes through network. Also we proposed a stability estimation method and applied that in an optimized version of ad hoc on-demand distance vector (AODV) routing algorithm by doing some modification at RAODV algorithm. In our algorithm namely Modified Reverse Ad Hoc On-demand Vector (MRAODV), the route request packet didn't change and it is like as AODV, but rout reply packet must be changed for route stability estimation purpose. By doing this we applied link stability in RAODV for decrease overhead of discovery and maintenance of routing. Our protocol also increased the packet delivery ratio in mobile ad hoc networks.
