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.

Pattern-MAC (PMAC) protocol, instead of having fixed sleepwakeups, the sleep-wakeup schedules of the sensor nodes are adaptively determined. The schedules are decided based on a node’s own traffic and that of its neighbors.

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.

OFDM(正交频分复用)技术实际上是MCM(Multi-Carrier Modulation，多载波调制)的一种。其主要思想是，将信道分成若干正交子信道，将高速数据信号转换成并行的低速子数据流，调制到在每个子信道上进行传输。正交信号可以通过在接收端采用相关技术来分开，这样可以减少子信道之间的相互干扰(ICI)。每个子信道上的信号带宽小于信道的相关带宽，因此每个子信道上的可以看成平坦性衰落，从而可以消除符号间干扰。而且由于每个子信道的带宽仅仅是原信道带宽的一小部分，信道均衡变得相对容
