基于CoAP的无线传感器网络与互联网的互联研究

无线传感器网络与其他网络的互联是无线传感器网络研究热点方向之一,基于IPv6的全IP化互联方式是当前最受关注的焦点。本文介绍了在IP化无线传感器网络上实现REST风格服务的受限应用层协议CoAP,比较了CoAP与HTTP的不同和性能差异,最后提出和总结了基于CoAP的无线传感器网络与互联网的两种互联方式。

Research on Integrating Wireless Sensor Networks with the Web Based on CoAP

Integration between wireless sensor networks （WSNs） and other networks has interested many researchers in both academic and industrial communities, especially the approach to realize IPv6 in WSNs. This paper focuses on RESTful＇ WSNs. It introduces the Constrained Application Protocol （CoAP）, reports the results of an experiment showing the difference of performance between CoAP and HTTP. It also proposes two approaches based on CoAP to integrate WSNs with the web.
