A traffic aware, energy efficient MAC protocol for wireless sensor networks

— In this paper, we focus on the problem of designing an energy efficient MAC protocol for wireless sensor networks and propose a novel scheme, named as TEEM (Traffic aware, Energy Efficient MAC). Inspired by S-MAC protocol, probably the most well-known sensor MAC scheme for energy efficiency, the proposed TEEM is also based on the concept of ‘listen/sleep modes cycle.’ However, unlike the S-MAC where the duration of listen and sleep modes are fixed, our TEEM protocol makes these durations adaptive by utilizing ‘traffic information’ of each node, and hence achieves a significant decrease in power consumption. Through implementation in Motes sensors, the presented TEEM is evaluated and compared to S-MAC as well as the IEEE 802.11-like protocols.
