الملخص EN

This paper proposes a MAC protocol for Radio Frequency (RF) energy harvesting in Wireless Sensor Networks (WSN).

In the conventional RF energy harvesting methods, an Energy Transmitter (ET) operates in a passive manner.

An ET transmits RF energy signals only when a sensor with depleted energy sends a Request-for-Energy (RFE) message.

Unlike the conventional methods, an ET in the proposed scheme can actively send RF energy signals without RFE messages.

An ET determines the active energy signal transmission according to the consequence of the passive energy harvesting procedures.

To transmit RF energy signals without request from sensors, the ET participates in a contention-based channel access procedure.

Once the ET successfully acquires the channel, it sends RF energy signals on the acquired channel during Short Charging Time (SCT).

The proposed scheme determines the length of SCT to minimize the interruption of data communication.

We compare the performance of the proposed protocol with RF-MAC protocol by simulation.

The simulation results show that the proposed protocol can increase the energy harvesting rate by 150% with 8% loss of network throughput compared to RF-MAC.

In addition, the proposed protocol can increase the lifetime of WSN because of the active energy signal transmission method.
