关于网络节点稳定性控制仿真研究

摘要

A new adaptive weighting clustering algorithm of Ad Hoc network is proposed.Firstly,the comprehensive consideration is carried out from mobility of network node,node degree,residual energy,node reputation,and distance between nodes,and stability of generated cluster structure is ensured.And then,the variation of relative position and coverage density of cluster structure are evaluated.Moreover,the node with the maximum weight as cluster head via calculating weight of node is compared and selected,and reasonable plan for cluster amount and number of cluster member is carried out.Finally,the stability control of network node is completed.Simulation results show that the algorithm can ensure the stability of network node.It prevents interrupt of communication process effectively and improves network stability effectively.%对网络节点的稳定性进行控制,能够更好的提高网络运行稳定性.对网络节点稳定性的控制,要通过对网络进行安全加权分簇,选取权值较大的节点作为簇首,并对簇的数目和簇成员个数进行合理的规划,完成对网络节点稳定性的控制.传统方法将筛选后的节点进行比较,求取簇的个数,但忽略了对其进行合理规划,导致控制效果不理想.提出一种新型的AdHoc网络自适应安全加权分簇算法.首先从网络节点移动性、节点度、剩余能量、节点信誉度和节点间距离五方面进行综合考虑,保证生成的簇结构的稳定性,评价节点间的相对位置变化,簇结构的覆盖密度,通过计算节点的权值,比较选取权值较大的节点作为簇首,并对簇的数目和簇成员个数进行合理的规划,完成网络节点的稳定性控制.仿真结果表明,提出的算法能够保证网络节点的稳定性,有效防止了通信过程的中断,有效提高了网络稳定性.
