1. A system comprising:
a plurality of end nodes, wherein
the end nodes include a sensor node and an actuator; and
an apparatus for synchronizing the plurality of end nodes in a vehicle, the apparatus comprising:
an emitter for emitting a synchronization signal to the end nodes;
a receiver for receiving one or more response signals from the end nodes; and
a processor configured to provide the synchronization signal via the emitter, wherein
the actuator is configured to perform an actuation triggered by reception of the synchronization signal, and
the sensor node is configured to generate a sensor signal prompted by reception of the synchronization signal, wherein
the synchronization signal is configured to address a subset or all of the end nodes to:
enable a synchronized action of the addressed end nodes, and
trigger a generation of one or more response signals from the end nodes in response to the emitted synchronization signal; and
the end nodes are configured to be in a standby mode with a decreased energy consumption and to wake up upon receiving the synchronization signal.
