ETI-MAC: An Energy-Harvested Transmitter-Initiated MAC Protocol for Wireless Sensor Networks


The paper proposes an Energy-Harvested Transmitter-Initiated MAC Protocol for WSNs (ETI-MAC). ETIMAC takes advantage of the benefits of transmitter-initiated schemes and employs the low power listening (LPL) method with small preamble messages so that each sensor node in the network can predict its next sleep duration based on the harvested energy rate value, thereby lowering the duty cycle by making use of its accumulating residual energy. The simulation results show that the proposed protocol outperforms compared to the old PSEHWSN scheme.
