Design of Techniques to Enhance the Services for Mobile Video-on-Demand Applications

The current generation of mobile clients have incessant demand for services. Providing Video-on-Demand (VoD) services to these clients require a new paradigm. This paper presents an architecture for Mobile Video-on-Demand. Several schemes that reduces the load on the video server, thereby increasing the number of requests that need to be served is proposed. The Distributed Indexing reduces the storage load on the server and reduces the time to search for a video. The Chaining Technique increases the acceptance of requests and thereby reduces the rejection rate. Two types of hand-offs are defined :Video Server Hand-off and a Client Hand-off. These provide the continuity of services to the mobile clients. The Windowing Scheme which includes Session Management is proposed. This scheme control the flow of segments. All these schemes have been simulated and the results are presented.
