Wireless Communication Technologies in Internet of Things: A Critical Evaluation

Internet of Things has gained the attention of almost everybody due to its capability of monitoring and controlling the environment. IoT helps making decisions supported by real data collected using large number of ordinary day-to-day devices that have been augmented with intelligence through the installation of sensing, processing and communication capabilities. One of the main and important aspects of any IoT device is its communication capability for transferring and sharing data between other devices. IoT devices mainly use wireless communication for communicating with other devices. The industry and the research community have proposed many communication technologies for IoT systems. In this paper, the authors present the results of an in-depth study carried out on the benefits and limitations of these communication technologies.
