定向MANET网络MAC层关键技术研究

Research on MAC's key technologies in directed MANET

基于定向天线的MANET网络容量虽具有配对通信增益,但其灵活的通信拓扑也使得MANET网络协议设计非常复杂。目前定向MANET网络MAC层技术在应用上还存在不少问题。本文从系统的角度对工程实际中需要解决的定向MANET网络MAC层关键技术做了研究,涉及通信拓扑管理、链路管理、配对协议、时隙分配算法4个方面。针对某些问题提出了解决所需综合考虑的因素,以及一些解决思路,并举例加以说明,以期抛砖引玉,推进定向MANET网络实用化进程。

Although network MANET which is based on directed antenna has pairing gain in communication capacity,yet the design of directed MANET＇s protocol is very complicated due to its free and varing communication topology,consequently there are still some problems to present current MAC technologies into MANET with directed antenna.In this article,some should-be-solved key engineering technologies of MAC in directed MANET were described from system point of view,involving communication topology management,link management,pairing protocol and time slot allocation algorithm.Some necessary elements which should be considered for compositely solving these issues were put foward.Ideas for solving other corresponding problems were proposed,and illustrated with examples also,to intrigue related researchers to put their heart to these problems and consequently,to promote the application process of directed MANET.
