Consensus Congestion Control in Multirouter Networks Based on Multiagent System

Abstract EN

Due to the unbalance distribution of network resources and network traffic, congestion is an inherent property of the Internet.

The consensus congestion controller based on the multiagent system theory is designed for the multirouter topology, which improves the performance of the whole networks.

Based on the analysis of the causes of congestion, the topology of multirouter networks is modeled based on the graph theory and the network congestion control problem is described as a consensus problem in multiagent systems.

Simulation results by MATLAB and Ns2 indicate that the proposed algorithm maintains a high throughput and a low packet drip ratio and improves the quality of the service in the complex network environment.
