Ad hoc On-Demand Distance Vector (AODV), is based on distance vector routing, that guarantees loop-free routes by using sequence numbers that indicate how new, or fresh, a route is and select minimal length path according to less number of hop-count, as a distance metric. However, AODV routing protocol itself does not consider the current load of node’s in the process of route discovery, so it may result in congestion in the path and localized network congestion. In This paper proposed mechanism combines improvement of Random Early Detection [RED] by self parameter adjustment for performance optimization and with AODV protocol optimization by diverting packet transmission from congested route to non congested route, to improve network performance. Experimental result shows that it achieves high throughput and higher packet delivery ratio in Mobile Ad hoc network.
