In this paper, the authors propose TBB-MAC, an enhancement for Medium Access Control (MAC) protocol based on the token bus in Wireless Sensor Networks (WSNs). In this type of networks, sensors are spatially correlated and they often sense and collect the information and send it to the sink. In this paper, they design an innovative contention-based MAC protocol to provide long network lifetime. Their ideas help wireless nodes at sleep mode as much as possible to avoid major energy waste causes, such as idle listening, collision and overhearing. They want to show that, TBB-MAC can be an efficient method to reduce redundant transmissions in sensor networks, thus diminishing energy consumption and transmission delay.
