Abstract :
In this poster, we propose a novel energy efficient asynchronous MAC protocol for WSNs-WX-MAC. WX-MAC supports nodes to exchange their sampling schedules by query and report mechanisms. With the aid of neighbors´ information and strobed preamble approach, WX-MAC shortens senders´ preamble before data transmission and reduces nodes´ wakeup duration. WX-MAC not only reduces the energy consumption on the senders and targets, but also decreases the possibility of overhearing on the surrounding neighbors, leading to a further energy conservation. Preliminary simulations have shown that WX-MAC saves more energy than B-MAC, Wise MAC, and X-MAC.
