Broadcasting XML data via wireless channel is an efficient way for disseminating semi-structured information and attracts more interests of researchers. As different parts of a piece of XML information have different access probability, fragmenting the original XML data intelligently can improve the broadcast efficiency. Existing works focus on splitting XML documents according to the queries in on-demand mode, but the split results have redundancy. In this paper, we propose a novel scheme of fragmenting XML data in push-based broadcast. First, a linear algorithm, whose idea is from an efficient document splitting algorithm in on-demand mode is provided. Then, an optimized algorithm with a little more time complexity is proposed. Existing air indexing and scheduling techniques are proved to work well under this scheme. Finally, experimental results show that the fragment methods improve the broadcast efficiency a lot by bringing a little auxiliary information.
