Framework and Implimentation of an Agent Based Congestion Control Technique for Mobile Ad-hoc Network

In Mobile Ad hoc Networks (MANETs) obstruction occurs due to the packet failure and it can be successfully reduced by involving congestion control scheme which includes routing algorithm and a flow control at the network layer. In this paper, we propose to framework and implimentation an agent based congestion control technique for MANETs. In our technique, the information about network obstruction is collected and disseminated by mobile agents (MA). The nodes are classified into four categories based on its traffic class. The MA measures the get in line length of the various traffic classes and the channel disagreement and estimates the total congestion metric to find the minimum congestion level in the network. The congestion metric is applied in the routing protocol to select the minimum congested route. By simulation results, we show that our proposed technique attains high delivery ratio and throughput with reduced delay when compared with the presented technique.
