Power Conserving and Access Efficient Indexes for Wireless Computing [chapter]

Dik Lun Lee, Qinglong Hu, Wang-Chien Lee
2000 Information Organization and Databases  
Moreover, we introduce two access efficient indexing methods, cache schedule and integrated signature, for a wireless data dissemination system that incorporates both of broadcast and on-demand services  ...  These indexing methods show that battery power consumption in mobile clients can be significantly reduced with some access time overhead.  ...  Logically, it maintains a database and provides data to its mobile clients. Each data item in the database is uniquely identified by its primary key which is a distinct number assigned by the MSS.  ...

Public Data Dissemination via Broadcasting

Michael Wisely, Sahra Sedigh Sarvestani, Ali R. Hurson
2015 Journal of Information Processing  
Broadcasting disseminates data from a server in a way that is analogous to AM/FM radio or television broadcasts. Devices tune in to wireless channels to fetch data items from a broadcast.  ...  Despite these issues, broadcasting is a scalable and efficient method for disseminating data to mobile clients.  ...  In a client-server environment, an MSS disseminates data from a data source to mobile hosts.  ...

Allocation of Data Items for Multi Channel Data Broadcasting in a Mobile Computing Environment [chapter]

Agustinus Borgy Waluyo, Bala Srinivasan, David Taniar
2004 Lecture Notes in Computer Science  
Utilising broadcast mechanism for query processing in a mobile computing environment is very much desirable due to its scalability.  ...  In this paper, we propose a broadcast ordering scheme at the server side, which aims to minimize query access time of mobile clients. We concern with data broadcast over multiple wireless channels.  ...  We assume to utilize Global Index, a multi channels indexing technique that we have proposed in [10] .  ...

Optimizing Query Access Time over Broadcast Channel in a Mobile Computing Environment [chapter]

Agustinus Borgy Waluyo, Bala Srinivasan, David Taniar
2004 Lecture Notes in Computer Science  
Broadcast strategy is known as an effective mechanism to disseminate database information to mobile clients.  ...  In this paper, we propose analytical models for both query access times over broadcast channel and on-demand channel.  ...  For future work, we will vary the size of broadcast data items, and ordered the items in a way to meet majority requests.  ...

Query Management for Efficient Data Access in Wireless Environment

Seema Verma, Author Rakhee, Savita Kumari
2011 International Journal of Computer Applications  
To retrieve such broadcasted data mobile client submit a query to broadcast channel and get responded in sequential manner. Hence query plays central role in wireless communication.  ...  In such computing system server continuously broadcast data over air channel without waiting for client's response and client retrieve only the data pertaining to him.  ...  She thanks faculty and staff there for extending help to prepare this paper.  ...

Efficient data access to multi-channel broadcast programs

Wai Gen Yee, Shamkant B. Navathe
2003 Proceedings of the twelfth international conference on Information and knowledge management - CIKM '03  
Little work, however, has considered the access structures necessary for making effective use of the additional channels. We propose various indexing schemes for a multi-channel broadcast program.  ...  Broadcast is a useful data dissemination technique because of its scalability, but is lacking when it comes to response time.  ...  Indexing the Scheduled Data In this section, we offer two alternatives for indexing a multi-channel broadcast program, assuming that the index is a balanced n-ary tree (e.g., a B+-tree).  ...
