摘要
移动多跳Ad hoc网络能以自组织的方式,利用Wi-Fi和Bluetooth技术在本地范围内有效的进行通信。文中通过仿真,提出了在有GSM/UMTS的支持下,异地的多个Ad hoc网络之间通信时一种有效的桥接方式,并且对网络拓扑进行分析,结果表明它具有小世界网络的两个显著特征:高聚合性和较短的特征路径长度,这对提高通信效率和节省带宽资源有很好的指导意义。
Mobile multi--hop ad hoc networks allow efficient communications with Wi-Fi and bluetooth technologies in a self-organizition way. In this paper, a efficient bridge-link way for communications among between many ad hoc network partitions with the support of GSM/UMTS links is proposed, then the topology of network is analyzed and the simulation results indicate that it has two distinguishing characteristics of small world networks： a strong local clustering while still retaining a small average distance between two nodes, it may be of guidance in raising communication efficiency and saving bandwidth resource
