| dc.description.abstract | The advances in mobile devices and wireless communication techniques have enabled anywhere, anytime data access. In Broadcast Disks, one of the important components of this environment is the server with broadcasting capabilities. Data are fetched from the server and being broadcasted to the air. Mobile users keep listening to the air and catch the data that they maybe interested. There are many strategies proposed for efficient broadcast delivery such as disk broadcasting (Chang & Yang, 2002; Acharya, 1998). Disk broadcasting approach has developed an algorithm which arrange the sequence order of data to be broadcasted. This generate the sequence of data with the policy where data that frequently accessed are called “hot” and less frequently access are called “cold”. However, based on disk broadcasting approach, some broadcast sloted in the broadcast are empty in which we referred as unused slots. The unused slots are considered as a waste of bandwidth thus increasing the client’s waiting time. Therefore, we propose a new data organization for the server which is to eliminate the unused slots in the broadcast and will fill them with data selected according to their popularity. We show by case study and simulation that our data organization scheme has resulted bandwidth utilization and reducing the clients’ average waiting time. | en_US |
