This work presents an efficient scheme for processing queries on location dependent data in a cellular mobile environment. It is developed around the theory of cellular automata (CA) which act as a search engine and implements computation for query processing that either can be done at the network base station or at the mobile unit depending on the requirement specified by the service provider. The scheme also ensures efficient handling of disconnection problem due to hand-off. The experimental results confirm that the overhead & delay, query processing, in the proposed scheme is much less than that of the existing schemes.
