a carrier sense multiple access with collision avoidance (CSMA/CA) based MAC protocol, called nanoMAC, suitable for low bit-rate, low-power wireless devices with high efficiency

X-MAC, a low power MAC protocol for wireless sensor networks (WSNs). Standard MAC protocols developed for duty-cycled WSNs such as BMAC, which is the default MAC protocol for TinyOS, employ an extended preamble and preamble sampling.
