| 摘 要： | RWP模型作为节点仿真移动模型被广泛应用在传统移动自组织网络研究中,而机会网络作为移动自组织网络的一个分支,具有不保证连通的网络拓扑特性,这种特殊性可能导致RWP模型不适合作为仿真机会网络的节点移动模型.结合复杂网络理论中平均度与平均聚类系数的概念,对RWP模型仿真数据与实验数据进行了对比分析.分析结论指出,在平均度相近的条件下RWP模型的平均聚类系数与实验数据有明显的差异,因此RWP模型不适合作为描述机会网络的移动模型.

| Abstract: | RWP Mobility Model is Widely used in regular MANET research as simulation mobility model,Opportunistic Networks is a branch of MANET,with a characteristic that does not guarantee network topology connectivity,this may lead RWP model not suitable as a simulation model of Opportunistic Networks.In this paper,using concept of average degree and average cluster coefficient in complex network theory,the RWP model simulation data and experimental data are compared and analyzed,and author concludes that when the average degree of RWP model is similar to the experimental data,the clustering coefficient have significant differences,so RWP model is not suited to simulation mobility model of Opportunistic Networks. |
