摘要： 针对无线Mesh网络中传输链路负载不均衡的问题,使用混合整数线性规划问题表示联合信道分配、路由度量以及网络接口分配的优化模型,提出一种快速收敛的启发式算法(ILSG)求解规划问题。ILSG算法使用考虑网络连通性以及负载均衡的贪婪算法生成可用初始值,将初始值代入局部迭代搜索法(ILS)获得规划结果并确定网络资源分配方案。仿真结果表明:ILSG算法可以以更快的收敛速度得到优化模型的分配策略,在保证网络公平性的基础上提升了网络性能。

Abstract: To solve the problem of load imbalance in Wireless Mesh Network (WMN), an optimization model is used in this work. This model jointly considers channel assignment, routing and interface allocation by making use of mixed integer linear programming. A heuristic algorithm (ILSG) with fast convergence rate is proposed to solve the programming problem. The ILSG algorithm considers network connectivity and load balance to get initial value, which is plugged into iterated local search algorithm to obtain the resource allocation results. Simulation results indicate that the ILSG algorithm can not get the allocation results with a faster convergence speed, but also improve the network performance on the basis of ensuring the fairness.
