An Integrated Signature Indexing Technique for Information Broadcasting over the Multi-level Wireless Channels

Abstract

Mobile device has limited battery power, the minimization of the access time and tuning time for the broadcast data is an important problem. There have been many research efforts that focus on minimizing access time and tuning time by providing indexes on the broadcast data. This paper proposes two level energy efficient signatures indexing techniques over the multichannel to reduce power consumption for wireless broadcast. The two-level signature scheme is used for indexing the information frames. At the first level, the integrated signature is used to index the indexes about the information. At the second level a simple signature is used to index the indexes about the information.
