Analysis of vehicle sensor network
[Keywords] network, sensors, vehicles, research, node, data, wireless, motion, movement, through
Through the vehicle sensor equipment, vehicles, two types of nodes can sense information: vehicles and vehicles of the information in the vehicle information including vehicle operation within the state, the car’s location, speed, etc.; vehicles, the information is mainly environmental information, including temperature, humidity, atmospheric index, as well as travel information, including road traffic, road conditions, etc. In addition to sensor devices, the driver is actually a highly intelligent ‘sensors’, through the saw and heard, to perceive complex events, such as detection of traffic accidents, dangerous driving and other important events of each vehicle sensor nodes sensing different regions, different times of the data, these data can be perceived as a large number of applications to provide valuable data to support. Vehicles, sensor networks have broad application background, typical applications include traffic safety [1], traffic flow management [2] and urban monitoring [3].
As a special wireless sensor networks, vehicle sensor has its own unique network, which determines many of the traditional wireless sensor network solution can not be applied to the vehicle sensor networks, the need to carry out new research, a new optimal design.
This paper reviews the vehicle sensor networks, sensor networks, more discussion of the characteristics of the vehicle to discuss the design of its challenge to bring the final introduction of key technologies in the vehicle sensor networks research progress and some typical applications.
A vehicle sensor network architecture
Shown in Figure 1, the vehicle sensor network node by the mobile vehicles and fixed road side infrastructure components. Through the vehicle radio communication equipment, vehicles node has wireless communication capability. When two nodes in a
