A krill herd optimization based fault tolerance strategy in MANETs for dynamic mobility

Mobile ad hoc network (MANET) is the multi-hop network, infrastructure less network with autonomously self-organizing in the distributed network. In case of node failure or link failure, MANET has the capacity to self-heal by changing the topology dynamically. There are many issues due to its dynamic nature, with the change in topology which leads to more routing. In multi-hop networking it uses the routing protocols such as AODV and DSR are due to its dynamic infrastructure and high mobility. The krill herd bio - inspired optimization algorithm in MANET is proposed for the dynamic network for the efficient power saver and reducing the routing process by the local and global optimization. The local search can be calculated by the sensing distance in KH algorithm to find the nearest neighbors with in the infrastructure. The local optimization uses AODV protocol and in global optimization, the DSR protocol is used for the power consumption. The node failure or node link failure can be detected by the KH algorithm as random diffusion and motion influencing other node.
