Abstract
In this article we elaborate on reality considerations when designing and implementing application tailored TDMA-FDMA medium access protocol with guaranteed end-to-end delay. We highlight importance of considering underlaying hardware and software components when designing communication protocols for resource constrained platforms. We also show that by combining medium access protocol, bootstrapping, and time synchronization mechanisms within the link-layer, we can limit on average clock drift in the network to 0.5 μs, as well as achieve 81% energy efficiency while keeping collision probability at its minimum of 1%. Finally, we conclude with challenges and lessons learned in real-world deployment of TDMA/FDMA based link-layer with guaranteed end-to-end delay in WSN.
