Abstract:


Background & Objective: With the rapid improvement in mobile communication technology, the query processing has gained a huge interest from the mobile users. But the requirement of high efficiency and high quality service in query processing is still increasing. A query processing scheme in hybrid wireless network is proposed in the present work.

Method: In the proposed query processing scheme, normal nodes generate queries as query issuing node. Some infrastructures are assumed as authorized information centre. Each authorized information centre maintains a database to store the response of the queries. A routing algorithm is proposed in the present work to select a route between the query issuing node and its nearest authorized information centre. The query issuing node sends the query through the selected route and receives the response of the query from its nearest authorized information centre through the same route.

Conclusion: The performance of the scheme is elaborated qualitatively and quantitatively. The qualitative performance is studied in terms of storage and communication overhead. The quantitative performance is studied in terms of waiting time, traffic and success rate. It is compared with the existing query processing schemes in hybrid wireless network and ad hoc network.
