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]

"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."

"Road transport (British English) or road transportation (American English) is the transport of passengers or goods on roads. ...
Transportation.
Transport on roads can be roughly grouped into the transportation of goods and transportation of people. In many countries licencing requirements and safety regulations ensure a separation of the two industries.
The nature of road transportation of goods depends, apart from the degree of development of the local infrastructure, on the distance the goods are transported by road, the weight and volume of the individual shipment, and the type of goods transported. For short distances and light, small shipments a van or pickup truck may be used. For large shipments even if less than a full truckload a truck is more appropriate. In some countries cargo is transported by road in horse-drawn carriages, donkey carts or other non-motorized mode. Delivery services are sometimes considered a separate category from cargo transport. In many places fast food is transported on roads by various types of vehicles. For inner city delivery of small packages and documents bike couriers are quite common.
People are transported on roads either in individual cars or automobiles, or in mass transit by bus or coach. Special modes of individual transport by road like rickshaws or velotaxis may also be locally available." [Road transport. Wikipedia]

The vector stencils library "Telecommunication networks" contains 32 clipart images of telecommunication network devices and equipment for drawing telecom network diagrams.
"A telecommunications network is a collection of terminal nodes, links and any intermediate nodes which are connected so as to enable telecommunication between the terminals.
The transmission links connect the nodes together. The nodes use circuit switching, message switching or packet switching to pass the signal through the correct links and nodes to reach the correct destination terminal.
Each terminal in the network usually has a unique address so messages or connections can be routed to the correct recipients. The collection of addresses in the network is called the address space." [Telecommunications network. Wikipedia]

The vector stencils library Alarm and access control contains 80 symbols of digital proximity equipment, locking hardware, and access control equipment.
"An alarm device or system of alarm devices gives an audible, visual or other form of alarm signal about a problem or condition. Alarm devices are often outfitted with a siren." [Alarm device. Wikipedia]
"An access control point, which can be a door, turnstile, parking gate, elevator, or other physical barrier, where granting access can be electronically controlled. Typically, the access point is a door. An electronic access control door can contain several elements. At its most basic, there is a stand-alone electric lock. The lock is unlocked by an operator with a switch. To automate this, operator intervention is replaced by a reader. The reader could be a keypad where a code is entered, it could be a card reader, or it could be a biometric reader. Readers do not usually make an access decision, but send a card number to an access control panel that verifies the number against an access list. To monitor the door position a magnetic door switch can be used. In concept, the door switch is not unlike those on refrigerators or car doors. Generally only entry is controlled, and exit is uncontrolled. In cases where exit is also controlled, a second reader is used on the opposite side of the door. In cases where exit is not controlled, free exit, a device called a request-to-exit (REX) is used. Request-to-exit devices can be a push-button or a motion detector. When the button is pushed, or the motion detector detects motion at the door, the door alarm is temporarily ignored while the door is opened. Exiting a door without having to electrically unlock the door is called mechanical free egress. This is an important safety feature. In cases where the lock must be electrically unlocked on exit, the request-to-exit device also unlocks the door." [Access control. Wikipedia]

This vehicular network diagram sample was drawn on the base of picture illustrating the post "LED Traffic Signals and Vehicle Lights for Optical Broadband Communications" from the blog "Terranautix".
"Visible Light Communication (VLC) is a rapidly emerging field that focuses on the use of light sources (between 400 THz and 800 THz) for the primary purpose of broadband communications. In order to transmit data over light, the light source (transceiver) is pulsed on and off rapidly to create a data stream, similar to fiber optic communications, but in the wireless form, or “Free-Space Optical Transmission“. By pulsing lights many thousands (and millions) of times per second, data transmission occurs at a rate undetectable by the human eye. Optical receivers convert the light pulses to an electronic signal on the receiver end. The Light Emitting Diode (LED) is the primary form factor currently undergoing extensive research."

Used Solutions
Cisco Network Topology. Cisco icons, shapes, stencils and symbols
Cisco Network Topology represents the arrangement of worldwide recognized and standardized Cisco network symbols, icons, shapes, and stencils which help visualize the schemes of computer networks. Any equipment used in Cisco networks is also named a node and network topology diagram represents the scheme of connection the used nodes. Cisco Network Diagram illustrates how the signals enter on the networked devices and how the data spread within a network from one device to another. These diagrams are useful for engineers while constructing computer networks and working with them. Cisco Network Diagrams solution included to Computer and Networks area of ConceptDraw Solution Park contains quick-start templates, professionally designed samples and examples, and numerous libraries with a lot of predesigned vector design elements, icons, and shapes of Cisco equipment, components, devices, links which provide for ConceptDraw DIAGRAM users a perfect possibility of simple and quick drawing Cisco Network Diagrams and Schematics, Network Designs and Maps of any complexity.The 3D pictorial street maps are used as road maps, route maps, locator maps, transit maps, directional maps, tourist maps with points of interest (POI).
"A point of interest, or POI, is a specific point location that someone may find useful or interesting. ...
Most consumers use the term when referring to hotels, campsites, fuel stations or any other categories used in modern (automotive) navigation systems. ...
The term is widely used in cartography, especially in electronic variants including GIS, and GPS navigation software. In this context the synonym waypoint is common.
A GPS point of interest specifies, at minimum, the latitude and longitude of the POI, assuming a certain map datum. A name or description for the POI is usually included, and other information such as altitude or a telephone number may also be attached. GPS applications typically use icons to represent different categories of POI on a map graphically." [Point of interest. Wikipedia]
