Intelligent Data Receiver Mechanism for Wireless Broadcasting System

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 result in further needs for managing access modes to let the mobile hosts procure highest benefit through the disconnections. In this paper, we propose a new broadcast indexing structure, Data Receiver Indicator (DRI), which allows mobile clients to determine the time interval of active and sleep mode for connection according to turnaround time. Our goal is to develop an intelligent data retrieve protocol that allows mobile users to acquire more valuable data with less power consumption within a limited turnaround time. Our performance results show that DRI substantially outperforms the traditional indexes and especially gets 75% saving on waiting time. Therefore, with our approach, users may acquire more valuable data with less power consumption and reduced waiting time which means faster query and response.
