Abstract
Research activity in the area of medium-access control protocols of
wireless sensor networks (WSN) has grown dramatically in the past few years.
A number of MAC protocols are proposed to achieve energy efficiency upon
the limitation of WSN which are usually deployed in a special environment,
assigned with long-term work, and supported by limited battery. It is found that
there is a trade-off between energy efficiency and transmission delay, thus duty
cycle of fixed sleep/listening MAC protocols has to be adjusted carefully to
achieve the best performance. Taking the challenge to design an adapted
listening mechanism, A-MAC is designed to adaptively and dynamically adjust
the duty listening time based on traffic load. With A-MAC, it can achieve more
power efficiency in low traffic load and much less transmission latency
comparing to existing MAC protocols. We simulate A-MAC, and the
simulation result shows that A-MAC can significantly prolong the lifetime of
network ...
