| 摘 要： | 针对MANET网络中分簇拓扑管理开展研究。为了提高网络逻辑拓扑的稳定性,对经典的Lin-Gerla分簇算法进行改进。改进算法充分考虑了通信系统中节点的移动性,引入了相对运动的概念,选取运动较为稳定的节点成为簇头,使得在随机方向模型下的移动网络的稳定性有所加强。针对可能出现分簇集中度过高的问题,提出了一种应用于簇维护阶段快速的簇分裂方法。最后对改进算法进行了仿真和性能分析。

| Abstract: | The cluster topology management in the MANET network is studied in. The classic Lin-Gerla clustering algorithm is improved to increase the logical topological stability. By considering the node mobility in the communication systems, the notion of relative motion is introduced, and the nodes more stable are chosen as the cluster-heads, which effectively increases the stability of mobile network with Random Direction Model. Regarding the possible high concentration, a fast cluster splitting method is proposed for cluster maintenance. The simulation and performance analysis for the improved algorithm are given. |
