Abstract

Broadcast disk technology has become a popular method for data dissemination in wireless information systems. However, factors such as intentional periodic disconnection by the mobile hosts (MH) result in further needs for managing access modes so as to let the mobile hosts procure highest benefit through the disconnections. We address this issue in this paper and propose solutions for the MH to retrieve the broadcast data. Our performance results show that the proposed algorithms indeed achieve almost the optimal performance, but require only 5---30% of the cost of an algorithm that is otherwise designed.
