TSMP

TSMP, an acronym for Time Synchronized Mesh Protocol is a communications protocol for self-organizing networks of wireless devices called "motes". TSMP was pioneered by Dust Networks. TSMP devices stay synchronized to each other and communicate in timeslots, similar to other TDM (time-division multiplexing) systems. Such deterministic communication allows the devices to stay extremely low power, as the radios only turn on for the periods of scheduled communication. The protocol is designed to operate reliably in a noisy environment. It uses frequency hopping to avoid interference -- the packets between TSMP devices get sent on different radio channels depending on time of transmission.

Time synchronized mesh networking has also gained acceptance in applications that require extremely high reliability and ultra long battery life, typically measured in years. New protocols like WirelessHART from the HART Communications Foundation have been standardized in the Industrial market for manufacturing process monitoring and control. It is widely expected that more mainstream applications like wireless sensors for urban infrastructure monitoring as well as building management will be based on some form of a time synchronized mesh networking technology to ensure the sensors will function reliably for many years.
