摘　　要：基于REST架构的CoAP协议是6LowPAN协议栈中的应用层协议,可运行在内存受限和计算能力有限的嵌入式设备中,并具有请求响应工作模式和可靠的数据传输性能,在物联网领域中具有极大的发展潜力。然而,现有基于CoAP协议设计实现的客户端较为复杂,影响了它在该领域的应用和推广。针对这一现状,提出一种新型CoAP应用架构,该架构通过在CoAP协议基础上增加一个链接服务器,实现CoAP客户端和CoAP服务器之间的通信,简化了基于CoAP架构的客户端设计,为推广CoAP架构在物联网领域的应用提供了参考模型。The CoAP protocol based on REST architecture is the application layer protocol in the 6LowPAN protocol stack,can run on embedded devices with limited memory and computing capability,and has the request-respond work mode,reliable data transmission performance,and great development potential in the IoT field.However,the current client designed and implemented on the basis of the CoAP protocol is relatively complex,and its application and popularization in the IoT field are affected.In view of this situation,a new CoAP application architecture is proposed.In this architecture,a link server is added on the basis of the CoAP protocol,so as to realize communication between the CoAP client and CoAP server,simplify the design of the client based on the CoAP architecture,and provide a reference model for the promotion of CoAP architecture application in the IoT field.
