UDA: Update driven approach for Continuously Moving Objects

In the present scenario location updating is main problem in mobile applications. Mobile clients will be spread based on location hierarchy. Updating all mobile clients’ information at single database server faces overhead problem. To overcome this, in our approach we are providing server hierarchy for load balancing. Mobile clients generally send continuous information to servers. But if movement is local then the local server will have responsible to update data. If movement is global then central server will send data to all. Using this approach load is balanced. We develop efficient query evaluation/reevaluation and safe region computation algorithms in the approach. The experimental results show that UDA substantially outperforms traditional schemes in terms of monitoring overhead, CPU cost, and scalability while achieving close-to-optimal communication cost.
