Time Synchronized CommunicationAll node-to-node communication in a TSMP network is transacted in a specific time window. Commonly referred to as Time Division Multiple Access, or TDMA, synchronized communication is a proven technique that provides reliable and efficient transport of wireless data. A critical component of any TDMA system is time synchronization – all nodes must share a common sense of time so that they know precisely when to talk, listen, or sleep. This is especially critical in power-constrained applications like WSNs where battery power is often the only option and changing batteries can be costly and cumbersome. A common sense of time enables many network virtues: Bandwidth can be pre-allocated to ensure extremely reliable transmission and zero self-interference; transmitting nodes can effectively change frequencies on each transmission and the receiving node can keep in lock-step; bandwidth can be added and removed at will in a very predictable and methodical way to accommodate traffic spikes; and many others.
