The Internet has transformed our lives, serving as a digital backbonefor communication, media and Web-based interaction among human users. It has, however, begun to evolve into the Internet of Things (IoT), interconnecting constrained devices such as sensors, actuators and miniaturised computing platforms. Aided in large part by advances in decreasing hardware costs, better battery, radio and computational technology, these kinds of connected IoT devices have rapidly begun to proliferate. The resulting traffic generated and exchanged by IoT devices is expected to dwarf that produced by humans. However IoT devices exhibit significant differences in terms of computational and storage capacities, wireless radio networks and communication protocols. Integrating them into the Internet is not straightforward, in terms of device addressing, reachability as well as data representation and transfer. In many IoT domains, there are already deployed networks, devices and sensors based on legacy technology, that the IoT is compelled to integrate. All this has led to the emergence of IoT gateways in playing a central role for integration and interoperability, in ensuring interconnection and end-to-end communication with different kinds of IoT devices and networks.
