基于“适应活性”的 QoS 组播路由算法
A QoS MULTICAST ROUTING ALGORITHM BASED ON ‘ADAPTIVE LIVING’
摘要
Abstract
In special application scenarios such as the natural disasters and the wars,communication networks are difficult to provide stable services to users because it is prone to the effects of physical attacks and multi-constraints.Traditional QoS routing algorithms are based on steady network,they are no longer suitable under the condition of physical attacks and multi-constraints.Aiming at this problem,in the paper we put forward and calculate for the first time the ‘adaptive living’model to comprehensively measure the dynamic service performance of network nodes and their connecting links.Furthermore,by improving the ant colony optimisation algorithm we put forward an ‘adaptive living’-based QoS multicast routing algorithm.The algorithm can consider comprehensively the selection path of the link and the service performance of nodes in combination with the external environment,service requirements and network status,while inheriting the advantage of traditional ant colony optimisation,it solves the problem that the external environment affects the variation of node performance which in turn causes the path selection cannot reach QoS optimum.Result of simulation on MATLAB shows that the algorithm can keep away from low performance nodes when the networks performance varying,and can fast and effectively select QoS optimal path.关键词
