摘要: 无线Mesh网的集中式网络控制结构,由位于有线网中的控制中心监测Mesh网拓扑变化和用户的性能需求,并计算从无线路由器到网关的路径。根据这一结构,提出了一种基于蚂蚁算法的带宽公平分配路由算法。该算法可以通过平衡流量负载最大化网络利用率,并对每用户提供公平的带宽分配服务。仿真表明,该算法的结果非常接近理论最优解。

Abstract:

As the centralized management architecture adopted by wireless Mesh networks often results in unbalanced bandwidth and load allocation, this paper proposes a fair bandwidth-allocation routing algorithm based on the ant colony algorithm by introducing a fair routing evaluation standard named minimum per-user average bandwidth. In the proposed algorithm, the traffic load is balanced and the bandwidth is fairly allocated for each user by maximizing the minimum per-user average bandwidth with the aid of optimization function of ants' travelling. Simulated resuits indicate that, as compared with the existing algorithms, the proposed algorithm may result in fairer bandwidth allocation though both the complexity and the average path length increase.

Key words: Mesh network, ants algorithm, fair routing
