  In Networked Control Systems (NCS) impairments of the communication channel
can be disruptive to stability and performance. In this paper, we consider the
problem of scheduling the access to limited communication resources for a
number of decoupled closed-loop systems subject to state and input constraint.
The control objective is to preserve the invariance property of local state and
input sets, such that constraint satisfaction can be guaranteed. Offline and
online, state feedback scheduling policies are proposed and illustrated through
numerical examples, also in case the network is subject to packet losses.
