One of the toughest challenges encountered in Wireless Sensor Networks (WSNs) is the limited power resources, which directly affects the network services quality and the sensors lifetime. Therefore, the proposed protocols must prolong the network lifetime as long as possible by minimizing the major sources of energy waste duo to the idle listening (no sent or received packets by the sensor). In this paper we propose a new communication protocol based on IEEE 802.15.4 standard called Adaptive
more &raquo; ... y-cycle (AD-MAC) that aims at reducing the energy dissipation where the transceiver is waiting potential packets. AD-MAC protocol mainly intends to reduce the power consumed by sensors in Beacon-Enabled mode via a dynamic duty-cycling technique. AD-MAC protocol optimizes the sleep interval between consecutive wake-ups without negatively influencing network performance. This solution uses a new predicting mechanism to estimate the moment when the sensors wake up or sleep according to previous traffic load statistics. Simulation results via NS-2 simulator show that AD-MAC protocol outperforms IEEE 802.15.4 standard in terms of minimizing energy consumption, and Packet Delivery Ratio (PDR).
