Energy constraint long-range wireless sensor/ actuator
based solutions are theoretically the perfect choice to
support the next generation of city-scale cyber-physical systems.
Traditional systems adopt periodic control which increases
network congestion and actuations while burdens the energy
consumption. Recent control theory studies overcome these problems
by introducing aperiodic strategies, such as event trigger
control. In spite of the potential savings, these strategies assume
actuator continuous listening while ignoring the sensing energy
costs. In this paper, we fill this gap, by enabling sensing and
actuator listening duty-cycling and proposing two innovative
MAC protocols for three decentralized event trigger contro
l
approaches. A laboratory experimental testbed, which emulates
a smart water network, was modelled and extended to evaluate
the impact of system parameters and the performance of each
approach. Experimental results reveal the predominance of the
decentralized event-triggered control against the classic periodic
control either in terms of communication or actuation by promising
significant system lifetime extension.
