| 摘 要： | 本文在无线令牌环协议(WTRP)的基础上,提出了一种无线动态令牌协议(WDTP),以解决其网络拓扑适应能力差和管理控制复杂的问题.本文首先介绍了WDTP协议的工作原理,然后详细阐述了令牌的动态传递算法、子网的建立过程和令牌的管理维护技术,对WDTP协议和WTRP协议的性能进行了分析比较,并通过模拟仿真比较了两种协议对网络拓扑结构的适应能力.仿真结果表明,WDTP具有良好的网络拓扑适应能力,并因此提高了频率资源的利用率.

| Abstract: | A Novel Multiple Access Control Protocol named as Wireless Dynamic Token Protocol (WDTP) is proposed in this paper based on the Wireless Token Ring protocol (WTRP) .Firstly the principle of WDTP is introduced,and the dynamic token transfer algorithm, process of constructing subnet and the mechanism of token Maintenance are depicted in detail. And then the performance of WDTP is analyzed compared with WTRP. The adaptability of WDTP and WTRP to network topology is emulated. The emulation results show that WDTP has more ability of adapting to network topology than WTRP, thus it can improve the frequency efficiency. |
