What is wireless mesh network bridge?

Wireless mesh networks, an emerging technology, may bring the dream of a seamlessly connected world into reality.
Traditional networks rely on a small number of wired access points or wireless hotspots to connect users. In a wireless mesh network, the network connection is spread out among dozens or even hundreds of wireless mesh nodes that "talk" to each other to share the network connection across a large area.

A wireless ad hoc network is a decentralized type of wireless network, don't need center gateway.The network is ad hoc because it does not rely on a pre existing infrastructure, such as routers in wired networks or access points in managed (infrastructure) wireless networks. Instead, each node participates in routing by forwarding data for other nodes, so the determination of which nodes forward data is made dynamically on the basis of network connectivity. In addition to the classic routing, ad hoc networks can use flooding for forwarding data.

Mobile ad hoc networks
A mobile ad hoc network is a continuously self-configuring, infrastructure-less network of mobile devices connected without wires.

Vehicular ad hoc networks
VANETs are used for communication between vehicles and roadside equipment. Intelligent vehicular ad hoc networks are a kind of artificial intelligence that helps vehicles to behave in intelligent manners during vehicle-to-vehicle collisions, accidents.

Position-based routing
Position-based routing methods use information on the exact locations of the nodes. This information is obtained for example via a GPS receiver. Based on the exact location the best path between source and destination nodes can be determined.

Multi-hops (over 20 hops high speed mobility, up to 3 radios)
The throughput reduces about 5~8Mbps/each Hop. From the 5th Hop on, the Throughput will not reduce anymore. The throughput can be remained more than 120Mbps. Even after 10 Hops, the latency is still within 40ms. Each hop the distance can reach 20-30km, this can resolve the ultra long range transmission.

Self healing
Mesh networks are "self healing" since the network automatically finds the fastest and most reliable paths to send data, even if nodes are blocked or lose their signal.

Mesh infrastructure carries data over large distances by splitting the distance into a series of short hops. Intermediate nodes not only boost the signal, but cooperatively pass data from point A to point B by making forwarding decisions based on their knowledge of the network, i.e. perform routing. Such an architecture may, with careful design, provide high bandwidth, spectral efficiency, and economic advantage over the coverage area.

Wireless mesh networks have a relatively stable topology except for the occasional failure of nodes or addition of new nodes. The path of traffic, being aggregated from a large number of end users, changes infrequently. Practically all the traffic in an infrastructure mesh network is either forwarded to or from a gateway, while in ad hoc networks or client mesh networks the traffic flows between arbitrary pairs of nodes.
Applications
Mesh networks may involve either fixed or mobile devices. The solutions are as diverse as communication needs, for example in difficult environments such as emergency situations, tunnels, mining, oil rigs, battlefield surveillance, high-speed mobile-video applications on board public transport or real-time racing-car telemetry.

At the same time open a counter and interrupt the line beginning to return to the initial value. When the image signal inversion (black to white or white to black), the trigger rising / falling edge interrupt,the interrupt will counter these two values ??recorded on the count value corresponding to the reversal in this line coordinates.

So, when we placed the camera, do not be a long shot directly at the intense sun rays, in addition to also pay attention to let the camera away from heat, because of long working hours at high temperature environment, the camera can also occur aging, reduce the imaging results. There is little need to remind you that, if the camera where the ambient light is too strong or too weak, then the effect of camera imaging is often difficult to achieve the most satisfactory state; For example, if the ambient light is very dim, then the picture looks imaging camera very dark, the picture looks even be dark; Of course, if the ambient light is too strong, then the picture looks imaging camera will be white. Therefore, the selection of a suitable working environment light intensity video interaction, and the camera is not facing the light source in order to ensure there are good results.from dust invasion Espanol

With mobile phone technology and manufacturing capabilities are maturing, functional factor is no longer the most important factor considered by the designer, replaced by feelings of consumers. As consumers look first impression of the product, the consumer experience plays an important role. Therefore, design is increasingly becoming a major factor consumers to buy mobile phones, how the appearance of design in order to meet the emotional needs of the primary task of the consumer and aesthetic needs into the phone designers. Give people the appearance of different products in different psychological feeling, which we call the product image, it belongs to the consumer products Perception category [1]. When the image of the product appearance and expressed preferences match consumer psychology to meet the aesthetic and emotional needs of consumers, consumers will want to buy the product produced, and vice versa.
