CoAP and Its Performance Evaluation

Abstract

ConstrainedApplication Protocol (CoAP) is one of the lightest IoT connectivity protocol.It has been developed for IoT devices that has constrained resources such asmemory, processing power, battery etc. CoAP protocol is built on RESTarchitecture. It provides connecting internet of IoT devices with UDP protocol.CoAP is a Client-Server request/response messaging protocol. CoAP provides twomodes of operations: (i) non-confirmable, (ii) confirmable. In addition, itprovides four methods to communicate for different application requirements.And it has two ways to response a request. This paper deals with CoAP IoTmessaging protocol and presents its performance evaluation. In addition,performance evaluation of CoAP has been realized according to delay, throughputand energy consumption parameters.
