摘要
Abstract
Many devices in the Internet of Things are resource-constrained, which have small amount of memory space and limited computing ability, so the traditional HTTP protocol is too large and not applicable. Therefore, CoRE working group in the IETF proposes a CoAP protocol based on the REST architecture. CoAP is an application layer protocol of 6LoWPAN protocol stack. This paper describes the content, features, and interaction model of the CoAP protocol. Finally, with the Contiki embed-ded operating system used in the wireless network uIPv6 START KIT development kit, the CoAP protocol is implemented not on-ly on the browser side, but also on the client-side program developed by the author to strengthen the interaction with the data-base. The function of viewing the most recent data as well as the historic data on the Web interface is achieved.关键词
