 TSMP distinguishes itself from other time-slotted mesh-based protocols, in that time-slot timing is maintained continuously and enables a network to duty-cycle on a transmitter-receiver pair-wise basis, as opposed to putting the entire network to sleep for extended periods of time (as is done in a beacon-based protocol, such as DigiMesh).Dust Networks' underlying time synchronized mesh networking technology has been standardized by the HART Communications Foundation with the WirelessHART protocol, the International Society of Automation ISA100 standard and in internet protocol standards, such as IEEE802.15.4E MAC layer, and IETF 6TiSCh.Time synchronized mesh networking is marketed for applications that require reliability and ultra long battery life, typically measured in years.
