A new high rate adaptive wireless data dissemination scheme

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 is sent only from clients whose distance from the server does not incur a significant timing overhead for the acknowledgment of an item. Simulation results are presented which reveal satisfactory performance in high-speed environments with a priori unknown and dynamic client demands. Ó 2006 Elsevier B.V. All rights reserved.
