摘要： 当前Ad hoc网络的研究大多基于模拟环境,对于MAC协议的模拟,大型模拟软件存在使用困难、不够精确等不足之处.为了进行MAC协议的相关研究,设计了一个小型的Ad hoc网络MAC协议模拟器;它对物理信道进行模拟,以数据字节作为最小的模拟单位,比较适合MAC协议的研究;同时可以使网络运行可视化,便于MAC协议的早期开发与调试.本模拟器采用面向对象方法和多线程协议栈模型,具有很好的扩展性;采用收发器类解决了模拟中遇到的同步问题.设计了一种新的比较适合MAC协议模拟的流量模型.给出了模拟器的设计思路和相关的测试.

Abstract: Recently most researches on ad hoc network were conducted by simulation. As to the simulation of MAC protocol, the large simulation softwares are usually difficult to use and inaccurate. A small-size ad hoc MAC protocol simulator is therefore designed to study relevant network protocol, which simulates physical channel with data byte as minimum processing unit that is suitable for studying MAC protocol. With the network activities visualized, it is convenient for early development and debugging of MAC protocol. This simulator is designed with an object-oriented method and multi-thread protocol model to provide well its extensibility and introduce a class of RXMitter to solve the synchronization problem. In addition, a new traffic model is proposed which is more suitable for MAC protocol simulation. An implementation method and related tests are given to the simulator.
