Survey on wireless XML broadcasting system
نویسنده
چکیده
Wireless communication is blooming along with Internet access from mobile devices which is an essential criterion for information access from anywhere, any time and any device. In this survey, review on various technologies like pervasive computing, mobile communication systems, selective dissemination of information, with location and device independent information interchange specification like XML (Extensible Markup Language. Wireless XML based selective dissemination of information is done in two ways. They are push based and pull based systems. Push based system broadcast the XML information over the wireless channel in a periodic or aperiodic manner. Pull based system gathers request from mobile clients through uplink channel and broadcasts the corresponding XML data for request in the downlink channel. Major performance metrics for wireless XML broadcasting system are tune-in time and access latency. Since wireless system has restricted power and bandwidth, efficiently utilizing these resources is essential. Keywordswireless broadcasting; XML dissemination; mobile

Access Time Efficient XML Data Scheduling Algorithm for Wireless Broadcasting
Wireless broadcasting system is of major two types namely push-based and pull-based. Extensible Markup Language (XML) is used to represent any information due to its inherent potential features such as scalable, self-describing, etc. Hence XML is chosen as standard for information dissemination in wireless broadcasting systems. Push based system periodically broadcasts XML data over the wireles...

The main aim of this paper is to improve energy and latency efficiency of XML dissemination scheme for the mobile computing, which is based on Lineage Encoding, G-node and scheduling algorithm for streaming XML data in the wireless environment. In this paper we propose a new broadcasting scheduling algorithm Frequently Access First (FAF) which effectively organize XML data on wireless channels....
متن کاملOrganizing XML Data in a Wireless Broadcast System by Exploiting Structural Similarity
Wireless data broadcast is an efficient way of delivering data of common interest to a large population of mobile devices within a proximate area, such as smart cities, battle fields, etc. In this work, we focus ourselves on studying the data placement problem of periodic XML data broadcast in mobile and wireless environments. This is an important issue, particularly when XML becomes prevalent ...
