【摘要】 本文提出了一种将Ad hoc网络与蜂房网,主要是TD-SCDMA相结合而构成的移动自组织网络结构,阐述了无论在TD-SCDMA基站的覆盖区(包括高速率和低速率区域)或非覆盖区,只要移动终端能够形成自组织网络,该网络中的设备就可建立起与蜂房网的通信、相互间的直接通信、通过AP(Access Point)接入固定网络以及与不同区域内的终端间的正常通信等工作方式,也能够有效地解决通信系统的业务量均衡和平滑切换问题;文章还从路由选择和对公众蜂房网容量的影响等方面对本文系统作了分析和仿真,结果表明,移动自组织网络的应用将会扩大蜂房网的容量,为拓展3G系统的应用提供了新的空间。更多还原

【Abstract】 A new architecture combining cellular network especially TD-SCDMA with Ad hoc network is proposed. It is described that end-to-end communication can be directly established among mobile terminals, between mobile terminals and TD-SCDMA base-stations. Mobile terminals can also access fixed network by AP’s. This can be done even when communicating mobile terminals in different network or in different areas, i.e., in the high-rate area, low-rate area or dead area. In this combined communication system, the problems of service balance and smooth hand-off can also be solved effectively. Analysis and simulation concerning routing protocol and system capacity have been performed and the results show that with the proposed system, cellular system capacity can be increased as to promote the application of 3G systems.更多还原
