Improving route maintenance protocol using ACO

Ad hoc wireless networks consist of mobile network without base stations, and are characterized by a host in a highly dynamic network topology. The topology changes frequently due to host migration, signal interference and power outages, making the route maintenance a challenging consideration in designing routing protocols. Most of the existing protocols perform an end-to-end route discovery to establish a new connection for the communication during link breaks. Such route repair mechanism causes high control overhead and long packet delay in a dense network. In this paper an algorithm for routing in mobile ad-hoc networks based on ideas from the ant colony optimization is proposed. Ant behaviours match with node of ad-hoc network. Ant colony is also a distributed system as ad-hoc. Ants communicates indirectly by environment. There may be a possibility get solution for routing algorithm in ad-hoc networks by ant colony optimization. Mobile ad-hoc network consists of mobile hosts equipped with wireless communication devices. This algorithm is used to reduce the delay, increase the performance of the job and identify the shortest path from source to destination node.
