FLEETNET
[attachment=24064]
INTRODUCTION
Driving means constantly changing location. This, in turn, means a constant demand for information on the current location and specifically for data on the surrounding traffic. In particular, there is a demand for sensor data from other cars such as data on braking sent from a preceding car, for data on the traffic flow on a route, and for information about sites located along a route. To promote the development of such an inter-vehicle communication system “FleetNet-Internet on the Road” was introduced.
OBJECTIVES OF FLEETNET
The objectives of FleetNet are:
To develop a communication platform for inter-vehicle communications.
To implement demonstrator applications.
To develop promising introduction strategies and
To standardize the solutions found in order to improve drivers’ and passengers’ safety and comfort.
KEY FEATURES
Wireless multi hop ad hoc networking extends the ‘range of awareness’.
Considering unlicensed radio frequency bands allows for low cost data transmission.
Very low data transmission delay is suitable for cooperative driver assistance and safety related applications.
Vehicles are addressed according to their position inherently enabling position-based routing and location-based services.
Vehicle to vehicle and vehicle to fixed roadside station communication enables Internet access and Internet integration.
open solutions to be standardized and open to other vehicle manufacturers.
FLEETNET ROUTING
This is also called as position based routing.
FleetNet routing assumes that vehicles are aware of their geographical position. By making use of position-based routing strategies, an improved scaling behavior and adaptability with respect to large and highly dynamic networks can be achieved compared to non-position-based approaches
RADIO COMMUNICATION
Routing, sending the packets everything is done perfectly but this system needs an interactive tool in order to convey the messages to the driver. This gives rise to the introduction of radio communication systems. The requirements on the FleetNet radio communication system are:
1. support of high bit rates;
2. Robustness in case of high relative velocities;
3. Provisioning of multi hop connectivity even in low traffic density scenarios; and
4. Operation in unlicensed frequency bands.
