"Driver assistance systems are meant to support drivers with driving process in order to avoid traffic accidents, speed up the traffic and have a higher control over the traffic in general. There are a lot of systems which give support to the drivers, such as adaptive cruise control, traffic sign recognition, automatic parking, etc. ... the vehicular communication systems ... use the capacity of the vehicles to communicate, not only between them but also with infrastructures. All the information is collected and processed to offer use
ful services. Wireless Sensor Networks (WSN) are widely used in this area. With the incoming upgrades of these networks, they are becoming an attractive solution to give support with the communication mechanisms between vehicles."

This global vehicular network diagram sample represents the independent regional telematics network.
"Telematics typically is any integrated use of telecommunications and informatics, also known as ICT (Information and Communications Technology). Hence the application of telematics is with any of the following:
(1) The technology of sending, receiving and storing information via telecommunication devices in conjunction with affecting control on remote objects.
(2) The integrated use of telecommunications and informatics, for application in vehicles and with control of vehicles on the move.
(3) Telematics includes but is not limited to Global Positioning System technology integrated with computers and mobile communications technology in automotive navigation systems. ...

"Alarm triggers.
The individual triggers for a car alarm vary widely, depending on the make and model of the vehicle, and the brand and model of the alarm itself (for aftermarket alarms). Since aftermarket alarms are designed to be universal (i.e., compatible with all 12 volt negative ground electrical systems as opposed to one carmaker's vehicles), these commonly have trigger inputs that the installer/ vehicle owner chooses not to connect, which additionally determines what will set the alarm off."
