一种移动Ad hoc网络中实时语音通信方案的研究

Research of solution for real-time speech communication over mobile Ad hoc network

由于移动Adhoc网络具有广泛的应用前景,出现了基于移动Adhoc网络的实时语音通信需求。此文对一种移动Adhoc网络中的实时语音通信的方案进行了研究。针对语音通信的特点,分析了其在移动Adhoc网络中实现的技术重点,并从网络层面和应用层面2个方面给出了解决方案:在网络层面上,对移动Adhoc网络进行实时语音通信所需的QoS机制进行研究,并给出了实验仿真结果;在应用层面上,讨论了将VOIP技术移植到移动Adhoc网络上的方法。

Mobile Ad hoc network （MANET） has brightening prospects due to the need of supporting Real-time Speech Communication. Some works about a solution for Real-time Speech Communication over MANET are re- searched in the paper. Based on the characteristics of the Real-time Speech Communication, the paper analyzes the key point of its implementation on MANET, provides the solutions at network level and application level. At network level, it is the idea about QoS mechanism needed by the Real-time Speech Communication over MANET, and the simulation result is given; while at application level, it is the discussion about implementing VOIP over MANET.
