QoS routing algorithm for mobile ad hoc networks using ACO

Routing, the act of moving information across an Internet work from a source to a destination is one of the major issues in computer network literature. When it comes to mobile ad hoc network, the complexity increases due to various characteristics like dynamic topology, absence of centralized authority, time varying QoS requirements etc. The biggest challenge in this kind of networks is to find a path between the communication end points satisfying user's QoS requirement which is aggravated through the node mobility. Recent advances in wireless technology and availability of mobile computing devices with networking capabilities have generated a lot of interest in wireless ad hoc networks for quality of service (QoS) based multimedia applications. In this paper we propose a new on demand QoS routing algorithm ldquoant routing for mobile ad hoc networks (ARMAN)rdquo based on ant colony metaheuristic. The proposed algorithm will be highly adaptive, efficient and scalable and mainly reduces end-to-end delay in high mobility cases.
