Abstract

Objective: This paper tries to devise a new algorithm based on ACO as well as multipath routing in Adhoc Multipath Distance Vector (AOMDV) environment. Methods/Statistical Analysis: Routing is a technique of transmitting data from source node to the destination node. Path breaks frequently in MANET due to the moving nodes. Multipath Routing presents a solution towards this problem, because of the presence of alternative paths. So, communication does not halt. Ant Colony Optimization (ACO) is a newer field of swarm intelligence to tackle optimization problems. Findings: The new algorithm is named A-AOMDV and is compared with other multipath and unipath protocols. Some of the performance metrics are chosen to compare and evaluate the new routing algorithm with traditional algorithms like Throughput, Jitter, Number of packets send, End to End Delay, Packet Lost, Delivery Ratio. Based upon the obtained results, the comparison graphs have also been made while evaluating parameters. The results are very encouraging and the new algorithm has outperformed other algorithms used for the purpose of comparison. Applications: Data communication can take place through alternative paths using efficient multipath routing protocol and easily tackle problems of disconnections during data communication.
