基于NDIS的无线Mesh网络协议的研究和实现

摘要

为了将无线Mesh网络的应用推广到Windows平台,提出了一个基于NDIS的无线Mesh网络协议--NMP协议.在对NDIS架构分析和研究的基础上,针对无线Mesh网络的特点,设计了一套完整的协议架构,其中包含数据包管理、链路维护,握手、认证、路由、流控、动态配置等各个方面.基于NDIS的特点使NMP协议的实现与下层网卡无关,并能被编译成标准的设备驱动文件应用于Windows系列操作系统中.对NMP协议进行了编码实现和实际运用,实际搭建了一个多跳的NMP网络并进行了性能测试,测试结果表明了该协议性能优越.%In order to expending the usage of wireless Mesh network to windows operating system, NMP, as a kind of wireless Mesh network protocol based on NDIS, is presented. Based on the analysis and study of NDIS architecture, aiming at the characteristic of wireless Mesh network, a complete architecture of protocol is designed and proposed, which comprising several parts, such as management of packets, link maintenance, handshake, authentication, routing, flow control and dynamic configuration. The characteristic of grounding on NDIS makes the implementation of NMP independent ofthe lower network interface card, and can be compiled to Windows standard system files which can be applied to windows operating system. At last, the coding of NMP is implemented and then NMP is applied application. A multi-hop NMP network is constructed and performance tests are carried out on it. The results show NMP is very effective.
