Problem statement: In the last few years, the evolution of the mobile networks leads to the query processing in mobile computing an impressive research area. The mobile computing technology needs to offer more and different innovative services as the number of users of the mobiles were increasing. In this regard, this study proposed a new algorithm which increased the performance of the query processing system in mobile computing. Approach: We employed different servers for different job processing. The buffer was maintained in the mobile node and the cache is maintained in the query server as well as mobile server. Prioritization was given to the queries based on different parameters like priority given by the user, required bandwidth. Results and Conclusion: The parameters considered for performance measure are query efficiency, delivery ratio and average power consumption and the results show that the proposed algorithm performs better than the existing systems. The query efficiency is increased by 13%, delivery ratio is increased by 26% and average power consumption is reduced by 35% on an average.
