Investigate Communication Protocols for IoT Application: Sensor Based Review

Abstract

Internet of Things (IoT) is the hot topic in the field of technology nowadays. We want everything to be automated in our daily life. A huge revolution has been brought by IoT in the history of Internet. IoT enables smart devices to collect specific data and exchange data among them. Exchanging data between smart devices usually occurs through some IoT communication protocol. Efficiency of a protocol depends in so many things such as Data Packet Rate, Security, Bandwidth, Communication overhead, Support of Quality of Service (QoS) level. In this research, some IoT protocols will be compared based on their efficiency and the protocols can be MQTT (Message Queue Telemetry Transport), CoAP (Constrained Application Protocol), AMQP (Advanced Message Queuing Protocol). RuuviTag sensor (a wireless BLE device) will be connected to a mobile app though BLE (Bluetooth Low Ener-gy). Though these protocols data from RuuviTag sensor will be transmitted among clients. These protocols will be compared based on their implementation complexity, data accuracy, application scalability, security. These comparison metrices among protocols will reveal the efficient protocol. The findings of this research will facilitate to a better understanding of the efficiency elements that are involved with IoT communication protocol by illuminating their performance traits and potential drawbacks. This research aims to identify the most suitable protocol based on the specific requirements of the endeavor. By carefully evaluating and analyzing the needs of the investigation, this study will contribute to the selection of an ap-propriate communication protocol. This research analyses the gaps and barriers of selecting an efficient protocol, and in order to improve the process this research will propose potential directions for future research.
