摘要
为获得全控型无线mesh网络的最优控制品质,首先分析影响全控型无线mesh网络控制品质的因素主要为网络时延,而为了获得较好的控制品质必须取得最小的网络时延,建立了最小网络时延的相关优化模型,并应用分支边界算法求解,最后通过相关数值计算和仿真分析,由仿真结果可知通过调节网络节点个数和数据流成功获得信道的概率以及任意节点获得信道后传输成功的概率降低网络时延,从而明显改善整个全控型无线mesh网络的控制品质。
In order to procure the optimum quality of control for full-controlled wireless mesh network, the primary influencing factor network time delay is analyzed. In order to get the optimum quality of control, the minimum network time delay should be acquired, and the algorithm of branch and bound is given to solve this problem. According to the numerical simulation, the quality of control for the whole network system with decreasing the delay time can be optimized by adjusting the number of nodes, the average transmission hop counts, and the probability of successful channel access and transmission for random nodes.
