This
paper presents a new adaptive mobility-aware MAC protocol
for sensor networks (MS-MAC). The protocol uses any change
in received signal level as an indication of mobility and, when
necessary, triggers the mobility handling mechanism. By doing
this way, the new mobility-aware MAC protocol can work very
energy-efficiently when the network is stationary, whereas it can
maintain some level of network performance when there are
mobile sensors.
Adaptive Coordinated Medium Access Control (AC-MAC), a contention-based Medium
Access Control protocol for wireless sensor networks. To handle the load variations in some real-time sensor applications, ACMAC
introduces the adaptive duty cycle scheme within the framework of sensor-MAC (S-MAC).
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.
