Home Automation Protocol For IOT

Abstract

In the emerging world of 5G, Internet of Things is one of the advancing technologies. This allows communication between devices, as well as devices and Internet; thereby giving an automated world excluding human intervention. and easier. Remote controlling and monitoring the device status being most important part in the communication is now possible with IOT protocols. HTTP-2, COAP and MQTT are the protocols that help constrained devices to live longer life. Device connectivity to internet carries security factor is playing a key role. TLS (Transport Layer Security) over TCP provides security to these tiny devices along with providing stable connection to internet. The other factor is power management, as minimal processing is required in constrained nodes, HTTP-2 protocol allows these tiny devices to save power by processing minimal header format instead of big HTTP 1.1 header. This saves lot of power of constrained devices. All major IoT communication protocols are briefly described in this thesis and comparison among them for the different applications has been presented. For the comparison of this protocols different data traffic patterns have been used. Results with respect to bandwidth and data rate are also presented for different protocols. Results clearly show that COAP protocol consumes 3 times less bandwidth than the HTTP 1.1 and MQTT generate 9 times less data than the HTTP 1.1. From this thesis one can get an idea to choose suitable IoT protocol for a particular application. Thesis also shows implementations of modules related to some of the IoT protocols.
