摘要:The migration to wireless network from wired network has been a universal trend in recent days. Wireless broadcasting is a mechanism for dispersing identical information in the wireless mobile environment. In this paper, we propose an XML broadcasting scheme. The wireless XML data stream consists of sequence of integrated nodes, called Gnode. G-node is a unit structure which consists of node name, location path, child index, attribute index, lineage code, Attribute Value List and Text List. An encoding scheme, called Lineage Encoding, is defined to represent the parentchild relationships among XML elements as a sequence of bitstrings, called Lineage Code (V, H). The components of Gnode are used to process twig pattern queries at mobile clients efficiently. Twig pattern query involves element selections satisfying complex patterns in tree-structured XML data. Symmetric encryption technique is used for ensuring security at mobile clients. By adopting these techniques mobile clients can retrieve the required data satisfying the given twig pattern query and security is provided so that one mobile client cannot view other mobile clients information
