Adaptive schemes for location update generation in execution location-dependent continuous queries
An important feature that is expected to be owned by today s mobile computing systems is the ability of processing locationdependent continuous queries on moving objects. The result of a location-dependent query depends on the current location of the mobile client which has generated the query as well as the locations of the moving objects on which the query has been issued. When a location-dep...

متن کاملProbabilistic Continuous Update Scheme in Location Dependent Continuous Queries
It is difficult to maintain the exact location of mobile objects due to the limited resources in a mobile network. A consequence of this problem is that the update cost for a location-dependent continuous query for moving objects can be quite high using traditional methods. In this paper, we propose a probabilistic update method to maintain the fidelity of the query results without incurring si...
متن کاملAn Efficient Method for Generating Location Updates for Processing of Location-Dependent Continuous Queries
Recent advances in mobile computing and mobile communication technology have led to the emergence of many innovative mobile-computing applications. Some of them require providing support to location-dependent continuous queries ( LDCQs) on moving objects. The result of a location dependent query depends on the current locations of the moving objects. When the query is specified as continuous, t...
متن کاملEffective Management of Location Dependent Continuous Queries in Mobile Environment
Advances in wireless and mobile computing environments allow a mobile user to perform within a wide range of applications. For example, mobile users need to pull data about unfamiliar places or local life styles related to their location. Furthermore, a mobile user may be interested in getting location dependent query results periodically. We propose an algorithm for handling continuous queries...
