On-Demand Multimedia Broadcast for Asymmetric Wireless Communication

On-demand broadcast is an efficient wireless data dissemination method for mobile services.As the rapid growth of the mobile application,there is an increasing need for system to support large data dissemination.This paper investigates wireless on-demand broadcast algorithms.We propose a new scheduling algorithm called FMT(Fluent Media Transfer) which takes the flux of program,the program size,request count and even the waiting time all into the consideration.And it pays more attention on the efficient use of system bandwidth.The simulations show FMT performances well according to the design principle.
