We investigate XML query processing in a portable/handheld client device with limited memory in ubiquitous computing environment. Because of memory limitation in the client, the source XML data possibly of large volume is fragmented in the server and streamed in fragments over which query processing is done in the client. The state-of-the-art techniques employ the holefiller model in fragmenting XML data and processing queries over XML fragment stream. In this paper, we propose a new technique where an XML labeling scheme is employed instead of the hole-filler model. Through preliminary experiments, we show that our technique outperforms the state-of-the-art techniques both in memory usage and in query processing time. © Springer-Verlag Berlin Heidelberg 2007.
