Vehicular ad-hoc network

This VANET diagram example was drawn on the base of picture from the webpage "Security and Privacy in Location-based MANETs/ VANETs" from the Donald Bren School of Information and Computer Sciences, the University of California, Irvine. [ics.uci.edu/ ~keldefra/ manet.htm]
"A vehicular ad hoc network (VANET) uses cars as mobile nodes in a MANET to create a mobile network. A VANET turns every participating car into a wireless router or node, allowing cars approximately 100 to 300 metres of each other to connect and, in turn, create a network with a wide range. As cars fall out of the signal range and drop out of the network, other cars can join in, connecting vehicles to one another so that a mobile Internet is created. It is estimated that the first systems that will integrate this technology are police and fire vehicles to communicate with each other for safety purposes. Automotive companies like General Motors, Toyota, Nissan, DaimlerChrysler, BMW and Ford promote this term." [Vehicular ad hoc network. Wikipedia]

This diagram sample illustrates the cooperative vehicular delay-tolerant network operation.
"Delay-tolerant networking (DTN) is an approach to computer network architecture that seeks to address the technical issues in heterogeneous networks that may lack continuous network connectivity. Examples of such networks are those operating in mobile or extreme terrestrial environments, or planned networks in space.
Recently, the term disruption-tolerant networking has gained currency in the United States due to support from DARPA, which has funded many DTN projects. Disruption may occur because of the limits of wireless radio range, sparsity of mobile nodes, energy resources, attack, and noise." [Delay-tolerant networking. Wikipedia]
"Routing in delay-tolerant networking concerns itself with the ability to transport, or route, data from a source to a destination, which is a fundamental ability all communication networks must have. Delay- and disruption-tolerant networks (DTNs) are characterized by their lack of connectivity, resulting in a lack of instantaneous end-to-end paths. In these challenging environments, popular ad hoc routing protocols such as AODV and DSR fail to establish routes. This is due to these protocols trying to first establish a complete route and then, after the route has been established, forward the actual data. However, when instantaneous end-to-end paths are difficult or impossible to establish, routing protocols must take to a "store and forward" approach, where data is incrementally moved and stored throughout the network in hopes that it will eventually reach its destination. A common technique used to maximize the probability of a message being successfully transferred is to replicate many copies of the message in hopes that one will succeed in reaching its destination."

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. ...
