By Philip Branch That’s what the Australian Communications and Media Authority (ACMA) has done this week with a very timely occasional paper on the Internet of Things (IoT). As well as identifying issues of direct concern to the ACMA, the paper also includes an overview of the technology and its capabilities. The IoT is the bringing together of a very large numbers of devices, data and computing power through the internet. The internet at the moment usually has a human at one or both ends of the communication. In the IoT, most communications will have sensors, actuators, databases or cloud-based computing process at either end. It is the linking of data from a large numbers of devices to the tremendous computing power of the cloud that makes the IoT so interesting. Sensor networks and machine-to-machine communication have been around for quite some time now, but has mostly been over the cellular telephony network or over short range, mesh networks such as ZigBee. Generally, the processing of data generated by these networks has been reasonably straightforward, such as pollution monitoring or device tracking. But the linking of these devices to the internet opens up many new possibilities. Large scale deployment of sensor networks will generate vast amounts of data which can be moved via the internet to be processed using the huge resources of cloud computing.
