Abstract: One can imagine a lot of realistic scenarios, such as
home or factory automation, where a wide variety of sensors and
actuators form a wireless network in order to perform various
tasks. There is still a lot of work to be done to ensure scalable
and reliable functionality of such a heterogeneous network. We
present a MAC layer algorithm that ensures end-to-end latency
requirements while minimizing maintenance. We demonstrate
that our algorithm scales down the duty cycles along constrained
paths in such a way that nodes with more capabilities take
on more responsibility in meeting the end-to-end application
constraints.
