The most important part of the Internet of things is communication among the IoT devices. The Internet of Things covers a huge space of devices, networks and use cases that scale from a single constrained device up to a mass crossplatform devices of embedded technologies and cloud connecting in real time. There are numerous devices emerging into the network which give rise to the various new communication protocols that allow devices to talk each other in more connected ways. Communication protocols in IoT are introduced in order to provide an efficient, reliable and secure communication for different applications. Depending upon the nature of use, the number of IoT devices uses different protocols such as CoAP, MQTT, XMPP, and HTTP are used. Two of the most promising for small devices are MQTT and CoAP. In this research paper, evaluation and packet analysis of CoAP, MQTT is done on basis of various parameters. Using various tools, packet analysis and dissection of packets is done for deep analysis to understand the affecting parameters from which security can be compromised in relation to the communication protocol. For that reference, various parameters, flags that are essential for a protocol in an IoT environment are tested using tools and simulators.
