| 摘 要： | 研究了移动Ad Hoc网络的动力学同步行为.用特征值比R来衡量网络的同步能力,特征值比R越小,同步能力越强.结果表明最初该网络的特征值比R随聚类系数C的增加而增加,继续增大聚类系数,特征值比反而减小.特征值比随聚类系数并不是普遍的正比关系也不是反比关系,而是先增大后减小,明显存在一个极值.

| Abstract: | The synchronizability of mobile Ad Hoc networks is investigated in this paper. The synchronizability is measured by eigenratio R. A smaller value of eigenratio R leads to a better synchronizability. The results indicate that with the increase of clustering coefficient C, eigenratio R increases in interval, but with the process going on, eigenratio R decreases. The eigenratio varies with clustering coefficient reither in direct proportion nor in inverse proportion, but rises first and reduces later,so there aooears a clear maximum value in between. |
