Abstract:

Among mobile computing applications, location-based services are expected to be a big business for wireless operators. These services provide value added by considering the location of the user in order to give him/her more customized information. However, the processing of continuous location-dependent queries is still a subject of research. One of the key issues is how to update the answer presented to the user efficiently as it becomes obsolete very quickly. The goal of this paper is to analyze how to deal with situations where the answer cannot be updated with the desired frequency. We present several approaches to this problem and evaluate their performance.
