P. Udayakumar, Ranjana Vyas, O. P. Vyas . Token Bus based MAC protocol for Wireless Sensor Networks. International Journal of Computer Applications. 43, 10 ( April 2012), 6-10. DOI=10.5120/6137-8373
In this paper, we 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, we design an innovative contention-based MAC protocol to provide long network lifetime. Our ideas help wireless nodes at sleep mode as much as possible to avoid major energy waste causes, such as idle listening, collision and overhearing. We 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. Hence, the network lifetime can last longer and the sink receives events within shorter delays. We propose to apply our technique in S-MAC and T-MAC, the contention based protocols for WSN. By simulation and experimentation, we prove that TBB-MAC overpasses S-MAC and T-MAC in terms of energy consumption and transmission delay.
