摘要
Due to the increasing usage of small and low footprinted devices like mobile phones as clients of mobile information systems a new problem arises: How to determine the relevance of updates for a large number of mobile clients? In this paper we present an indexing scheme that represents conjunctive queries posed by the mobile clients in a trie. So, IDs of the clients are referenced by their queries and checking the relevance of an update can be efficiently done by a trie lookup. © Springer-Verlag 2004.
