Wireless Wide Area Networks (WWANs) is expected to provide actual bandwidth at change of location, e.g., vehicle continuously changes its location by fast moving, it is difficult for network providers to eliminate bandwidth changes over a large service area, it may be possible to map network bandwidth over repeated measurements on the road network. In this paper, we proposed earlier problem over bandwidth maps in a heterogeneous network. We show the bandwidth mapping concept of delivering an Internet services from on-board mobile routers to the user with an adaptive multimedia server for the emerging vehicular system for communication. Using the simulation, we detect the data, to improve in Quality of Service (QoS) that can be achieved by taking advantage of the geographical knowledge of bandwidth provided by the bandwidth maps and merging the 3G based technology with Vehicular (VANET). We find that our approach improves the frequency of disruptions in perceived QoS for multimedia applications in high-speed vehicular mobility.
Conclusion
The emerging WWANs do not guarantee bandwidth uniformity over the geographical coverage. More precisely, at any given time, it is possible to receive significantly different bandwidth from the same network provider at different locations of the same street. We have found that the past bandwidth information is a good indicator of the actual bandwidth experienced at a given location. While time of day also influences the mobile bandwidth, our analysis of empirical traces has shown that location appears to have a far greater influence than time. We have shown that it is not difficult for vehicular users to capture the past bandwidth knowledge in the form of geographical bandwidth maps for part of the road network frequently traveled. We have further demonstrated the usefulness of these maps with two representative case studies, adaptive multimedia and mobile router-based vehicular Internet. Our work has shown that the use of past location-specific bandwidth knowledge can significantly improve the QoS of multimedia streaming applications in high-speed mobility.
