Abstract This work proposes query optimization model using caching for Mobile Ad-hoc Networks MANETs. In the recent era the proliferation of mobile devices increases the high traffic on Internet. Furthermore the large number of smart-mobile devices is capable to carry considerable amount of data with them. Increasing storage capability of mobile devices has inspired us to perform effective query optimization on mobile database systems where small part of the central database can be cached on local mobile database for performing faster query processing. This further reduces the need of constant connectivity of the device to the central server which reduces the Internet traffic. In the query issuer retrieves data from the cached mobile database which minimizes the traffic at central database server. The main contributions of our work are three-folds. First we propose cache-based query optimization model for faster data retrieval and effective query processing. Second we propose two schemes for cached-broker namely Event-Driven Query caching EDQc and Location-Dependent Query caching LDQc. Third we conduct a performance study which demonstrates that in order to retrieve data faster in mobile environment and to avoid large number of connection to the server caching is one of the important concept.
