In mobile ad hoc networks (MANET), the existing route discovery may result in traffic overflow and overhead. In order to overcome these issues, in this study, the authors propose an ant based multipath backbone routing for load balancing in MANET. When the source wants to transmit data towards destination, it selects the multiple routes with maximum path preference probability using swarm based ant colony optimisation technique. The path preference probability is estimated based on next hop availability, delay and bandwidth. During route discovery, the nodes subjected to faults are found and the relevant path is skipped. Then the network load on the routes is balanced by an index by each backbone node to distribute the data traffic equally on the links from source to destination. By simulation results, the authors show that proposed technique reduces the network load.
