This paper discusses the issue of power conservation on mobile clients, eg, palmtop, in
wireless and mobile environments. It suggests that techniques using signatures are suitable …

Organizing massive amount of information on communication channels is a new challenge
to the data management and telecommunication communities. In this paper, we consider …

A signature file acts as a filtering mechanism to reduce the amount of text that needs to be
searched for a query. Unfortunately, the signature file itself must be exhaustively searched …

In a wireless environment, information is broadcast on communication channels to clients
using powerful, battery-operated palmtops. To conserve the usage of energy, the information …

Studies power conservation techniques for multi-attribute queries on wireless data
broadcast channels. Indexing data on broadcast channels can improve the client filtering …

Signature le has been shown to be a very good access method for text and multiattribute
retrieval 6, 13]. It has a low storage overhead and a simple structure. However its speed is …

Mobile computers and wireless networks are emerging technologies which will soon make
ubiquitous computing a reality. In the wireless environment, mobile clients may often be …

A superimposed coding method, frame-sliced signature file, is proposed, and the
performance of this method is studied and compared with that of other signature file …

The signature file access method has proved to be a convenient indexing technique, in
particular for text data Because it can deal with unformatted data, many application domains …

The signature approach is an access method for partial-match retrieval which meets many
requirements of an office environment. Signatures are hash coded binary words derived …
