Inter-vehicle communication systems

This vehicular network diagram example was drawn on the base of the picture "Inter-Vehicle Communication (IVC) systems" from the website of the Department of Electrical and Computer Engineering, the Ohio State University.

"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."

The vehicular network diagram example "Inter-vehicle communication systems" 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.

The vector stencils library "Cisco routers" contains 27 router symbols for drawing the Cisco computer network diagrams using the ConceptDraw PRO diagramming and vector drawing software.
"A router is a device that forwards data packets between computer networks, creating an overlay internetwork. A router is connected to two or more data lines from different networks. When a data packet comes in one of the lines, the router reads the address information in the packet to determine its ultimate destination. Then, using information in its routing table or routing policy, it directs the packet to the next network on its journey. Routers perform the "traffic directing" functions on the Internet. A data packet is typically forwarded from one router to another through the networks that constitute the internetwork until it reaches its destination node.
The most familiar type of routers are home and small office routers that simply pass data, such as web pages, email, IM, and videos between the home computers and the Internet. An example of a router would be the owner's cable or DSL modem, which connects to the Internet through an ISP. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common." [Router (computing). Wikipedia]
The example "Design elements - Cisco routers" is included in the Cisco Network Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park.

"Vehicular Ad Hoc Networks (VANETs) are created by applying the principles of mobile ad hoc networks (MANETs) - the spontaneous creation of a wireless network for data exchange - to the domain of vehicles. They are a key component of intelligent transportation systems (ITS).
While, in the early 2000s, VANETs were seen as a mere one-to-one application of MANET principles, they have since then developed into a field of research in their own right. By 2015, the term VANET became mostly synonymous with the more generic term inter-vehicle communication (IVC), although the focus remains on the aspect of spontaneous networking, much less on the use of infrastructure like Road Side Units (RSUs) or cellular networks."
