ACO-GA based routing algorithm for MANET

Abstract

MANET is made up of a collection of mobile wireless nodes, each node act as router as there is no central coordinator present in this network to ensure in network routing.In MANETmultiple paths are available for data transmission, but itis required to choosemost efficient path between multiple pathsby providing better Quality of Service(QoS).Routing in MANET network is a challenging task, because the topology of the network is frequently changes. This issue is addressed in this paper.Here we introduce new routing mechanism by using ACO and GA approach to satisfy quality matrix.By using ant algorithm to explore the network using intelligent ANT packets based on pheromone concentration. Multiple paths are generated by ant algorithm and best path is chosen for data transmission, if link failure is occurs while data transmission then genetic algorithm is used for handling link failure by selecting another backup path based on fitness value
