Communication Protocols for Smart Sensors in IoT Applications

Abstract

The advancements in the field of electronics and wireless technology have put forward the idea of the Internet of Things which can be rightly called the third industrial revolution The Internet of Things technology is about connecting and communicating with anything anywhere at any time. The concept of the internet of things can be fully materialized with the help of its supporting technologies including the smart sensors, processors, and highly efficient communication protocols. The smart sensor nodes communicate with the base stations using different communication protocols. A brief review of the requirements of the IoT systems are studies and the communication protocols for the short-range and long-range IoT applications are discussed and compared in this study. Various short range and long range communication protocols which are used for the IoT applications are summarized along with the range covered and the number of nodes that can be connected. The major requirements and constrains of communication protocols employed in IoT applications are discussed. The study concludes that the choice of technology to be considered for the implementation of an IoT system is deeply connected with the types of applications which specify the range to be covered, the number of devices to be connected, the operational bandwidth available, the rate of transmission and the cost of the system.
