An Ad Hoc routing algorithm of low-delay based on hybrid Particle Swarm Optimization

In the ad hoc network of high mobility currently, there exists the problem of the high delay. This paper proposes to apply particle swarm optimization (PSO) strategy to improve this problem. Firstly, we present a hybrid particle swarm optimization (HPSO) algorithm combining genetic algorithm (GA), which is suitable to be used in a routing protocol, and then establish an on-demand routing protocol based on the novel algorithm. Next, we realize this protocol on the platform of OPNET and make simulation experiments. Compared with AODV that is a preferable ad hoc on-demand routing protocol, the results show that the routing protocol based on HPSO decreases greatly the network delay in the high mobility environment.
