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]
The VANET diagram example "Vehicular ad-hoc network" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Vehicular Networking solution from the Computer and Networks area of ConceptDraw Solution Park.
