ABC Supported Handover Decision Scheme based on multi-PSO with Optimum Mutation
In this paper, a handover decision scheme with ABC (always best connected) supported is proposed. With knowledge of fuzzy mathematics and microeconomics introduced, application types, QoS (quality of service) requirements, access networks and terminals are described. With access network conditions, application requirements, user preferences to access network coding schemes, user preferences to access network providers, terminal velocities and terminal battery capacities considered comprehensively, an optimal handover solution of assigning N terminals to M access networks is found based on multi-PSO (particle swarm optimization) with optimum mutation. With the help of gaming analysis, Pareto optimum under Nash equilibrium of both user utility and network provider utility is achieved or approached for the found solution. Simulation results showed that it was effective.
