摘要
针对MANET多路径自适应流量分配,提出了蚂蚁寻优自适应多路径流量分配算法。根据反应路径质量的权重动态确定多路径流量的比例,使得网络资源充分利用;利用蚂蚁算法作为流量分配的最优解搜索策略,获得更优的分配结果;依据前次流量分配结果构造蚂蚁算法的初始信息素,提高搜索效率。仿真表明:该算法在平均端到端延迟、报文成功传输率、控制开销、负载平衡性能方面有一定的提升。
In order to adaptively allocate traffic among multi-path in MANET, a scheme called Adaptive Multi-path Traffic Allocation Based on Ant Optimization Algorithm is proposed, which dynamically determines the ratio of multi-path traffic by the path weights which reflect the quality of paths. By this way, the net resource is utilized sufficiently. This scheme uses ant algorithm, which speeds up the searching rate, as searching method for the optimization solution for traffic allocation. The initial information element of ant algorithm is constructed according to the former traffic allocation result, which further improves the searching efficiency. Simulation indicates that the scheme obtains better performance in average end-to-end delay, successful packets delivery ratio, cost control, traffic balance.
