Cooperative Diversity Selection Protocol Using Pareto Method with Multi Objective Criterion in Wireless Ad Hoc Networks

In cooperative diversity of ad hoc networks, the selection of the path pair becomes very important to achieve optimum performance. In this paper, it was created the cooperative diversity protocol by using Pareto method for multi objective criteria problems namely the signal to noise ratio (SNR) and load variance. Pareto method was used to find a nondominated solution by way of Continuously Updated. The non-dominated solution was chosen based on the smallest euclidean distance. The advantage of this protocol is to provide fair and the best path pairs of cooperative diversity. From the simulation results, it was obtained the path pairs for cooperative diversity is path S-11-D and S-28-D selected by the smallest value of euclidean distance that is 0.108 and 0.379. Furthermore, the reliability of protocol with Pareto method was compared with the scalarization method in the form of value of cumulative distribution function (CDF).
