Emerging protocol can help manage the Internet of Things — GCN
The ever-expanding networks of sensors and other machine-to-machine devices on the “Internet of Things” are creating huge stores of data for everything from traffic and weather monitoring to health care and finance.
And there will only going be more of them. Sensors, for example, will play a key role in the Obama Administration’s recently released National Strategy for Civil Earth Observations, a plan to increase the efficiency and effectiveness Earth-observations. Along with other steps toward streamlining the efforts of the 11 agencies involved in the observations, it calls for extensive use of sensors in gathering the data.
Of course, having all that data is one thing. Making sense of it — quickly — is another. One key is the emerging Message Queuing Telemetry Transport (MQTT) protocol, a lightweight messaging transport for machine-to-machine communications that recently was proposed as an OASIS standard.
OASIS in March began the process “to define an open publish/subscribe protocol for telemetry messaging designed to be open, simple, lightweight and suited for use in constrained networks and multi-platform environments.” The protocol, which consumes little power, is designed to help sensors and other devices — which tend to be low-power and low-bandwidth — communicate reliably.
