Abstract

In Machine-to-Machine (M2M) communications, an enormous number of devices are subject to the battery limitation. Recently, an attractive energy harvesting technology called energy beamforming has shown great potential to make wireless devices self-powering. Motivated by this, according to the IEEE 802.11ah, a group-based energy harvesting Medium Access Control (MAC) protocol with the strategy of AP scheduling is designed in the paper to address the energy shortage without much reduction in system throughput. In the proposed protocol, nodes first contend for the transmission opportunities, and then data and energy transfer simultaneously by the AP scheduling scheme. Multiple Power Beacons (PBs) are employed to group the nodes in order to reduce high collision probability. The simulation results show that the proposed protocol has significant improvement over the legacy scheme in terms of saturation throughput, received energy and consumed energy.
