小生境粒子群优化ABC支持型QoS组播路由机制
ABC supporting QoS multicast routing mechanism using niche particle swarm optimization
摘要
Abstract
To solve these problems that the ABC (always best connected) supporting QoS (quality of service) multicast routing mechanisms usually suffer from the problems of inaccurate link parameters , indescribable QoS parameters of user and the conflicting interests between users and operators ,a multi‐objective model based on user and operator of the game was proposed .Specifically ,this model characterized those indescribable parameters by using the fuzzy math theory and ensured the fairness between users and operators by using the theory of Nash equilibrium .To solve this multi‐constrained QoS multicast routing model effectively ,a multi‐objective optimization algorithm ,namely niche parti‐cle swarm optimization based on dynamic Pareto cluster analysis ,was developed .This algorithm em‐ployed clustering niche to keep diversity of the population ,and received high‐quality solutions as soon as possible by introducing the dynamic Pareto analysis .Finally ,a comprehensive simulation experi‐ment was conducted on the NS2 (Network Simulator 2) platform .Experimental results show that the proposed mechanism obtains satisfactory performance regarding credibility of path ,the utilities of us‐ers and network providers ,which explicitly verifies its effectiveness and feasibility .关键词
