Bluetooth is an excellent candidate for connecting devices in an Internet of Things (IoT) because it is widely employed in various smart devices and uses very little power, says the Bluetooth SIG's Errett Kroeter.
However, it currently is architected as a hub-and-spoke network, with devices communicating only with a single hub, while an IoT network requires a mesh architecture in which devices can communicate directly with each other, passing data along to its ultimate destination.
In March, the Bluetooth Smart Mesh Working Group held its first meeting to begin work on developing a standard for Bluetooth mesh networks.
Most equipment--any device that supports Bluetooth 4.0 and higher--would be able to use it, according to Kroeter. He says a new security model will be required because devices will be able to communicate directly with each other, and the range of devices may not be any greater than the current 300 feet.
The group is scheduled to publish a standardized solution in early 2016.
