Analysis of various light weight protocols in internet of things-a comparative study

Abstract

Internet of Things (IoT) incorporates the physical world with computing devices enabling them to be operate from remote region. Sensors and actuators with the assistance of communication protocols (MQTT, CoAP, HTTP, and REST) exchange the data, enabling the smart devices to interact with each other. These sort of devices having restricted limit, the protocols are intended to be handle low data transfer capacity, communication issues and high latency rate. In this paper, existing lightweight protocols in IoT are analyze based on eight different parameters(Architecture, Need of broker, Transport protocol, Security protocol, Scope, Design Methodology, Message size, Service levels) and these protocols can be used based on their application area.
