MFT-MAC : A Duty-Cycle MAC Protocol Using Multiframe Transmission for Wireless Sensor Networks

Abstract EN

In many sensor network applications, energy efficiency and latency are major design criteria because battery-operated sensor nodes limit network lifetime.

In this paper, we propose a new contention-based duty-cycle MAC protocol using a synchronized approach for use in wireless sensor networks.

In the proposed MFT-MAC protocol, we use a control frame that considers the number of DATA frames to be transmitted to the next node in order to improve the energy efficiency and reduce the end-to-end delay.

During the SLEEP period, each node transmits multiple DATA frames to the next node through the use of the control frame.

The performance of the proposed MAC protocol is confirmed through the use of NS-2 simulator.
