摘要
文章对ZigBee无线组网技术的优势及其协议的MAC层帧格式进行了分析。通过无线测控网络构建和MATLAB仿真,分析说明增加数据帧中有效数据位和采用多跳传输方式能够提高信道容量与网络容量。作者提出了一种容量和时延性能评价方案,经过理论分析与仿真结果表明:该评价方法系统地描述了室内无线网络的实时性能和容量性能,具有较高的可行性。
The advantages of the ZigBee wireless networking technology and the MAC frame form in the ZigBee protocol are analyzed in the article A WSN measuring system module is established. The simulation result shows that increasing the number of the bits in effect and applying multi-hop transition scheme can improve the channel capacity and the network capacity which are simulated by MATLAB. As a result, we predict an estimation scheme of capacity-delay relationship. The theoretical analysis and the simulation result depict that proposed scheme depicts the real-time performance of the wireless network systematically with a high feasibility.
