We present an XML data exchange technique suitable for mobile commerce systems involving thousands of mobile users and massive data loads. A key idea of our technique is that it is based on an XML information repository that is logically split into several disjoint data fragments. Thus, each mobile user's device can determine those parts of the information repository that are required for answering a given query locally at the device. The benefit of this local query processing is that our technique allows participating user devices to make their cached data fragments available to other participating devices and relieves the central information repository, resulting in a significant reduction of the overall data transfer and improved query response times.Furthermore, we provide an experimental evaluation showing that our technique outperforms other data exchange techniques in terms of both, data transfer and query response times. Special to our experiments, we simulate a changing user interest in the course of the experiments to capture a real world mobile commerce user behavior in a scenario with a high load of users and data.
