Constrained Application Protocol (CoAP) is one of the lightest IoT connectivity protocol. It has been developed for IoT devices that has constrained resources such as memory, processing power, battery etc. CoAP protocol is built on REST architecture. It provides connecting internet of IoT devices with UDP protocol. CoAP is a Client-Server request/response messaging protocol. CoAP provides two modes of operations: (i) non-confirmable, (ii) confirmable. In addition, it provides four methods to communicate for different application requirements. And it has two ways to response a request. This paper deals with CoAP IoT messaging protocol and presents its performance evaluation. In addition, performance evaluation of CoAP has been realized according to delay, throughput and energy consumption parameters.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
