Abstract

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.

Keywords

CoAP, performance evaluation, energy consumption, throughput, time delay
