Energy-Aware Multipath Routing Scheme Based on Particle Swarm Optimization in Mobile Ad Hoc Networks

Abstract EN

Mobile ad hoc network (MANET) is a collection of autonomous mobile nodes forming an ad hoc network without fixed infrastructure.

Dynamic topology property of MANET may degrade the performance of the network.

However, multipath selection is a great challenging task to improve the network lifetime.

We proposed an energy-aware multipath routing scheme based on particle swarm optimization (EMPSO) that uses continuous time recurrent neural network (CTRNN) to solve optimization problems.

CTRNN finds the optimal loop-free paths to solve link disjoint paths in a MANET.

The CTRNN is used as an optimum path selection technique that produces a set of optimal paths between source and destination.

In CTRNN, particle swarm optimization (PSO) method is primly used for training the RNN.

The proposed scheme uses the reliability measures such as transmission cost, energy factor, and the optimal traffic ratio between source and destination to increase routing performance.

In this scheme, optimal loop-free paths can be found using PSO to seek better link quality nodes in route discovery phase.

PSO optimizes a problem by iteratively trying to get a better solution with regard to a measure of quality.

The proposed scheme discovers multiple loop-free paths by using PSO technique.
