Interoperability and the easy exchange of data are major concerns in the buildup of the Internet of Things. To ensure those attributes, a set of commonly accepted standards will be needed. So do we need to create those standards, or do we already have enough standards and simply need to pick and choose?
Fostering standardization within the IoT is not a simple issue. Take wireless connectivity, for example. We already have numerous wireless standards in existence that are well developed and time tested. Bluetooth, WiFi, ZigBee, cellular (CDMA, GSM, LTE, etc.), and DECT are all being used in IoT designs.
The same is true of communications protocols. There are TCP/IP, MQTT, HTTP, CoAP, and a host of others in contention for sending messages and data between IoT devices and the cloud. Even in the data analysis side of things, we have SQL and Hadoop as database options.
So there are plenty of standards already. But that hasn't stopped the industry from trying to create new ones to address IoT issues. The new wireless standard Weightless has been created, for instance. Industry groups such as the Allseen Alliance and Open Home Gateway Forum have put their bid in for standards within their industry segment.
Official standards bodies have also weighed in. The EU came up with its IoT-A reference architecture. Now the IEEE Standards Association is trying to come up with its own IoT reference architecture. Groups such as the ITU and NIST are also keeping their options open for getting into the standards discussion.
It may well be that a new set of standards will be needed for the IoT.
