Research of routing optimization based on improved PSO algorithm in power communication network

This paper introduces an improved PSO algorithm for power communication network routing, which minimizes the cost of communication and improves the Quality of Service (QoS). In this paper, PSO algorithm is improved in two parts of the parameter inertia weight and the discrete idea is added to, so that it can easily run out the local optimum and provide high speed of convergence as well as for the proposed application. An example shows the feasibleness and effectiveness of the algorithm. And it is easier to get an optimal or nearly optimal solution in power communication network routing by using the presented algorithm.
