Abstract :Constrained Application Protocol insert ignore into journalissuearticles values(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: insert ignore into journalissuearticles values(i); non-confirmable, insert ignore into journalissuearticles values(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.
Keywords : CoAP, performance evaluation, energy consumption, throughput, time delay
