摘要
针对战术移动自组织网络(MANET)中不同优先级业务服务质量(QoS)保障问题,提出了一种基于节点可用带宽接入门限及负载均衡的QoS路由算法(BLQRA)。利用蚁群优化的思想通过设计改进的蚁群算法搜索出满足各QoS约束且耗费最小的路径。仿真结果表明,在网络参数动态变化的情况下,算法实现了源节点到目的节点满足各QoS约束条件路径的有效寻找,并且与传统的ACRA算法相比,BLQRA算法最终收敛到了耗费更小的路径上。
Aiming at QoS （Quality of Service） guarantee for different priority service in tactical MANET （Mobile Ad Hoe Network）, a QoS routing algorithm BLQRA based on available bandwidth access thresh- old and load balance of the nodes is proposed. Based on the idea of ACO （Ant Colony Optimization） , a modified ant colony algorithm is designed and implemented, thus to search the routes which could satisfy the requirement of minimum cost under the QoS constraints. Simulation results show that the proposed BLQRA algorithm could realize effective search of the route from the source node and the destination node under the condition of dynamic network parameters, and as compared with traditional ACRA algorithm, may eventually converge to a route of less cost.
