Multiple-Objective Optimization QoS Routing under Imprecise Network Information

In order to guarantee and optimize end-to-end Quality-of-Service (QoS) in heterogeneous and converged mobile Internet, a novel QoS routing algorithm proposed to optimize multiple QoS metrics on virtual Overlay platform based on Multi-Objective optimization is introduced at this paper. Because of the imprecise network information, the membership function and probability are combined to find a solution set to optimize the multiple QoS constraints. Simulation results confirmed that our scheme can balance the network resources better in addition to finding a QoS path than other traditional algorithms.
