We present an OPNET model that uses WiMAX technology to send video packets in an advanced inter-vehicle VANET environment. Our work focuses on real-time video streaming. A video model was created based on live traffics trace and then integrated into a WIMAX OPNET model. VANET mobility was modeled with a real world road map and VANET mobility simulators. We integrate an implementable controller over RTP to handle congestion control by setting a framework fit for future road safety development. Different mobility cases are studied and the performance measures such as end-to-end delay, jitter and visual experience are evaluated. Different design considerations are presented to enable designers to effectively build on and develop a realistic video VANET simulation model.

Wireless video communication is becoming increasingly popular these days with new applications such as TV on mobile and video phones. Commercial success of these applications requires superior video quality at the receiver. So it is imperative to analyze the effect of a wireless channel on a video transmission. The aim of this research is to analyze the video transmission over Rayleigh fading channels for various bit error rates (BER), signal to noise ratios (Eb/N0) and Doppler rates, and to suggest which source coding scheme is best at which BER, Eb/N0 and Doppler rates. Alternative schemes such as hybrid (digital/analog) schemes were considered and their performances were compared with pure digital communication. It is also shown that the combination of digital and analog video communication does not yield any better performance compared to pure digital video communication.

This research deals with annotations in scholarly work. Annotations have been studied by many people. A significant amount of research has shown that instead of implementing domain specific annotation applications a better approach is to develop general purpose annotation toolkits that can be used to create domain specific applications. A video annotation toolkit along with toolkits for searching, retrieving, analyzing and presenting videos can help achieve the broader goal of creating integrated work spaces for scholarly work in humanities research similar to existing environments in such fields as mathematics, engineering, statistics, software development and bioinformatics. This research implements a video annotation toolkit and evaluates it by looking at its usefulness in creating applications for different areas. It was found that many areas of study in the arts and sciences can benefit from a video annotation application tailored to their specific needs and that an annotation toolkit can significantly reduce the time for developing such applications. The toolkit was engineered through successive refinements of prototype applications developed for different application areas. The toolkit design was also guided by a set of features identified by the research community for an ideal general purpose annotation toolkit. This research contributes by combining these two different approaches to toolkit design and construction into a hybrid approach. This approach could be useful for similar or related efforts.
