Improving Network Performance using ACO Based Redundant Link Avoidance Algorithm

In the wide spread internet, response time and pocket loss are inappropriate due to network traffic, as a result the network efficiency becomes worst and the system provides poor Quality of Service (QoS). An optimal routing protocol, especially multipath may avoid such traffic in the network. But existing routing protocols, both single path and multi path, concentrates only on finding the routes based on any one or some set of metrics, that not always suitable for dynamic, cloud natured network environment. Ant Colony Optimization (ACO) based multipath routing protocol was suggested as an alternate to this problem by many researchers. The multipath ACO also provides same set of link(s) for the source to destination, so that traffic merging again becomes a critical problem. This paper proposes an optimal solution to avoid the problem of traffic merging in the network by removing redundant link in the route. The Proposed algorithm, called ‘Redundant Link Avoidance (RLA) algorithm’, is an ACO based multi path routing methodology, avoiding copious link in the suggested routes of ACO multipath protocol.
