The Westchester law provides exceptions for drivers using text messages in case of emergency or once they have pulled off the road, out of the flow of traffic.
A convenient method for transmission of short messages in case of emergencies in massive scales, is cell broadcasting.
Furthermore, this algorithm does not consider the recovery of synchronization messages in case of loss, therefore worsening the synchronization precision on real implementations.
Although the interference coordination can be improved, the number of signaling messages increases, radio cells need to support sensing mechanisms, and event-based systems (e.g., traps) are required to send messages in case of interference detection.
A second aspect is remote monitoring, with triggering of automatic alert messages in case of an LV threshold rise.
In this case, no extra message is generated, since the faulty process does not receive the TREE message and, in case of VCube-RB, upon detection of the failure, a new message will be retransmitted to the next correct process in the cluster, which will retransmit in the subtree only once.
The MAC sub-layer developed for this experimental study proposes a frame structure that jointly handles the periodic traffic for monitoring the sensing device status and the potential bursty traffic for alarm message propagation in case of intrusion detection.
This embedding process creates a new message, called stego message (stego image in case of images), with the same visual and statistical appearance of the cover message but containing the embedded message.
In August of last year, FCC Chairman Julius Genachowski introduced plans for a next-generation 911 service, which would support text, picture and video messaging in cases of emergencies.
