Cache Relocation for Vod in Wireless Network Using Mobile Agent Technology

Recent advances in mobile computing and wireless technologies resulted in the emergence of new services such as Video-on-Demand. However, high rates of disconnection, low bandwidth, and other problems still strongly affect the quality of such services. To address some of these challenges, we propose a new model for the caching of video content that takes advantage of the cooperation among distributed caching proxies containing hot VoD titles in wireless base and support station caches. Our model also considers the constant movement of mobile users. Mobile agents are used to transfer cached video content from one base station to another. As the user moves from place to place, a mobile agent can bring the user specific cache video content to his device’s cache or to the base station under which the user is currently located.
