Wireless technologies in IoT: Research challenges

Abstract

Internet of Things (IoT) is a technology to create smart world. To enable an IoT system, communication plays an important role. Everything in IoT depends on the flow of information. Many wireless technologies are available for the purpose but the choice for the right technology depends on the use case requirements. Reliability and availability of an IoT application is the outcome of reliable communication. Issues like scalability and heterogeneity present numerous challenges to the researchers. Mobility maintenance, packet delay, signal load, etc., are challenges that make reliable communication difficult and affect the quality of service. This paper presents the details of wireless technologies available for the IoT and discusses the open challenges and research issues in IoT.
