摘要
免疫克隆选择算法主要是用来解决抗原初次入侵时,免疫系统产生抗体,做出免疫反应,但是现有方案往往没有给出当相同的抗原或相似的抗原再次入侵的解决方案。针对无线Mesh网络中各种故障频繁发生的情况,提出的算法能利用抗原的相似性来解决拓扑控制中近似的错误容忍问题。利用改进后的克隆免疫算法,在对无线Mesh网络进行拓扑控制时,求解网络的较优功率分配,使整个网络既满足Mesh客户端节点到Mesh路由器节点的k连通,而且整个网络的性能也能达到较优。通过对实验结果的分析发现,在保证网络容错的前提下,网络各方面的性能达到较优。
The immune clone algorithm mainly deal with the antigen prime intrusion by the antibody. The immune system creates the antibody to bring the influence of immunity. However, most existing works don＇ t give the schemes which can deal with the intrusion once more. Towards the frequent fault in wireless mesh network, an improved im mune clone algorithm was proposed to solve the similar fault tolerance problem. The improved algorithm was used in the wireless mesh network topology control to solve the network＇ s optimum power distribution. So the whole network meets kconnected from the mesh client nodes to the mesh router nodes and the whole network＇ s performance was opti mum. Through the analysis of experimental results, the network achieved optimum performance of many aspects in the premise of ensuring the network fault tolerant.
