摘要
无线Mesh网络的路由技术是影响网络性能的一个关键问题。针对无线Mesh网络的QoS多约束路由算法难于找到最优路径的问题,提出了一种基于免疫算法的路由算法,利用免疫算法的寻优能力,实现了无线Mesh网络QoS多约束条件下的最优路径选择,并与基于遗传算法的路由算法进行了比较。实验结果表明,利用免疫算法获得满足QoS要求的最佳路径时,不容易陷入局部最优,且收敛速度快,性能优越,更符合无线通信实时性的要求。
Routing techonology is an important issue for WMN(wireless mesh network).The multiple constrained QoS(quality of service) routing algorithm for WMN is hard to find the optimal path.This paper presents a new method based on immune algorithm to solve the QoS routing for WMN and ensure the finding of optimal path quickly.Simulation results and comparison with genetic algorithm show that this algorithm is of high convergence speed and not easy in falling into local optimum,thus could meet the real-time requirements in wireless communications.
