Abstract :
This study presents the design and performance evaluation of a latency bounded and medium access control (MAC) scheme (abbreviated to LB-MAC) for wireless sensor networks that require time-critical communication. LB-MAC provides the predictability for an end-to-sink data delivery time through the time division multiple access (TDMA) multi-channel transmission frame assignment considering the routing path of a tree network. In addition, it uses the traffic-based slot assignment mechanism at every transmission frame to achieve energy efficiency. The feasibility and effectiveness of LB-MAC is demonstrated through extensive simulation based comparisons with prior research.
