Transmission frame assignment for latency-bounded data delivery in wsns

This paper presents the design and performance evaluation of a latency bounded and energy efficient 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 TDMA multi-channel transmission frame assignment considering the routing path of a tree network. The feasibility and effectiveness of LB-MAC is demonstrated through extensive simulation based comparisons with prior research.
