摘要
越来越多的物联网设备采用Zigbee技术和网络通信协议实现互联互通,但是Zigbee协议每片报文的最大长度仅为128字节,严重限制了长报文在Zigbee协议上的传输。针对此问题,本文提出了一种基于Zigbee的长报文传控协议,设计了能够满足长报文分片和重组需求的协议头部字段,开发了协议栈的程序,并加入了超时机制和滑动窗口来保证传输质量和速率。实验结果表明该协议能够使Zigbee完成可靠和快速的长报文传输,验证了其在嵌入式系统通信中的可行性、稳定性和可靠性。
More and more IoT devices are using Zigbee technology and network communication protocols to achieve interconnectivity.However,the maximum length of each message in the Zigbee protocol is only 128 bytes,which seriously limits the transmission of long messages on the Zigbee protocol.In response to this issue,this article proposes a Zigbee based long message transmission control protocol,designs protocol header fields that can meet the requirements of long message sharding and reassembly,develops protocol stack programs,and adds timeout mechanisms and sliding windows to ensure transmission quality and speed.The experimental results show that the protocol can enable Zigbee to complete reliable and fast long message transmission,verifying its feasibility,stability,and reliability in embedded system communication.
