Video Streaming and Multimedia Broadcasting Over Vehicular Ad Hoc NetworksNaeimipoor, Farahnaz 30 January 2013 (has links)
Video dissemination capabilities are crucial for the deployment of many services over
VANETs. These services range from enhancing safety via the dissemination of video
from the scene of an accident, to advertisement of local services or businesses. This work
considers the infrastructure-less scenario of VANETs and dissemination of video content
over this network environment, which is extremely challenging mainly due to its dynamic
topology and stringent requirements for video streaming.
This study discusses issues and challenges that need to be tackled for disseminating
high-quality video over VANETs. Furthermore it surveys and analyzes the suitability
of different existing solutions aimed towards effective and efficient techniques for video
dissemination in vehicular networks. As a result, a set of the most promising techniques
are selected, described in detail and evaluated based on standard terms in quality of
service. This thesis also discusses efficiency and suitability of these techniques for video
dissemination and compares their performance over the same network condition. In
addition, a detailed study on the effect of network coding on video dissemination protocols
has been conducted to guide how to employ this technique properly for video streaming
over VANETs. From this study, a summary of the observations was obtained and used
to design a new hybrid solution by deploying robust and efficient techniques in number
of existing protocols in an optimal manner. The proposed hybrid video dissemination
protocol outperforms other protocols in term of delivery ratio and complies with other
quality-of-service requirements for video broadcasting over vehicular environments.
