In this study, a resource-efficient communication mechanism is investigated for the cooperative adaptive cruise control (CACC) of vehicles subject to actuator delay and disturbances. Specifically, dynamic event-triggered (DECM) designed tracking error (spacing error, velocity acceleration error) based sampled-data feedback controller. Under DECM, transmissions sampled from preceding vehicle controller can be significantly reduced. Sufficient conditions stability CACC system are obtained...

Military heterogeneous networks often suffer from node or edge failures due to attacks, which lead whole network topology segmentation even paralysis.
