An adaptive wireless push system for high-speed data broadcasting

With the increasing popularity of wireless networks and mobile computing, data broadcasting has emerged as an efficient way of delivering data to mobile clients having a high degree of commonality in their demand patterns. This paper proposes a push system that continuously adapts to the demand pattern of the client population in order to reflect the overall popularity of each data item. The adaptation is accomplished using a simple feedback from the clients. We propose that the simple feedback from the clients can be sent at regular time intervals in order to avoid the overhead that would be an incurred for acknowledging all item broadcasts. Simulation results are presented which reveal satisfactory performance in environments where client demands change over time with the nature of these changes being unknown to the broadcast server
