Alliances have started consolidating in 2016, although we cannot expect the high-level mergers of groups to align leading wireless protocols.
Soon after the New Year, I noted the convergence of protocols, alliances and methods for the Internet of Things has been getting underway.
I know, stop laughing. Industry watchers have predicted this convergence for years, and yet the proliferation of standards and proprietary solutions proceeded each year.
However, in 2016 we saw HomePlug declare victory and transit remaining work to Wi-Sun. Similarly, the Connected Lighting Alliance declared it has accomplished its mission and closed down. The Open Interconnect Consortium and AllSeen Alliance merged to create the Open Connectivity Foundation (OCF).
Companies and alliances will continue to work on many different standards and protocols, but the market is harsh and will sort out winners and losers. Those alliances that do not get sufficient traction can drag on for a long time but become irrelevant to the larger market growth.
Beyond the convergence of some alliances, I see a convergence in the wireless protocols used for low-power devices. The market has been converging on IP-based solutions around UDP, CoAP and JSON objects with CBOR compression. This set of protocols is used in Lightweight M2M, IPSO Smart Objects, OCF as well as the ZigBee Alliances’ new dotdot language for IoT. Alliances like Fairhair are working to provide commonality in the network infrastructure and device bootstrapping for commercial buildings.
Convergence of these protocols is the first step for the market. It’s recognised that for lower power networks and battery-operated devices, existing protocols such as TCP, HTTP and XML needed some optimisations, and the Internet Engineering Task Force has been working for a number of years on these alternatives.
Now many of these groups are developing their own application data models on how, for example, a connected light bulb offers services and interacts with a light switch. In a converged world, there must be agreement on these object data models so a light from one manufacturer running on one technology can be controlled by a switch from another manufacturer on the same or even a different technology.
It helps to agree on what protocols and object models have some actual mindshare in the connected home market. Today shipments in this market are using the following technologies:
Dotdot is an IP translation of existing ZigBee device objects. It can run over any IP stack so it can unify existing ZigBee devices with those running over Thread, Wi-Fi or Bluetooth.
While I am hopeful to see the beginning of consolidation of some alliances in 2016, we cannot expect the high-level mergers of groups to align leading wireless protocols. The reality is manufacturers are making choices every day on what technologies and protocols are going to be used in their next-generation of products.
They do not like changing technologies or protocols, and they do not like leaving stranded devices. That means there is a built-in advantage for widely shipping technologies like ZigBee and its migration to dotdot.
If this can be done quickly and deployed to market, it can help to consolidate not only the underlying protocols in use, but also the object data models within the devices. Then we can have simplified interoperability and connectivity to our cloud and mobile devices.
