TSMP

From Wikipedia, the free encyclopedia

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.
