Abstract:

This paper proposes the formula analysis and math model of QoS routing index based on multi-object planning method.Then it presents a QoS routing algorithm based on NSGA-II.In this algorithm,the resource expenditure and load-distributed of network are optimized as object function.It balances load,makes good use of network resource,reduces congestion of network,and increases throughout with minimized network resource.Simulation results demonstrate the feasibility and efficiency of the proposed algorithm.

Key words: QoS routing, Non-dominated Sorting Genetic Algorithm-II(NSGA-II), multi-objective evolutionary

摘要: 基于多目标规划问题,给出了QoS路由指标的形式化描述及数学模型。提出了用NSGA-II算法来实现QoS路由,并采用网络资源消耗和负载分布为目标函数,使得算法在消耗网络资源最小的基础上,使负载均衡分布,合理利用了网络资源,降低了网络的拥塞,提高了网络的吞吐量。通过仿真实验表明该算法是可行的、有效的。
