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.

处理连续的位置相关查询:即时数据刷新

在移动计算应用中，基于位置的服务有望成为无线运营商的一大业务。这些服务通过考虑用户的位置来提供附加价值，以便为他/她提供更多定制信息。然而，连续位置相关查询的处理仍然是一个研究课题。其中一个关键问题是如何有效地更新呈现给用户的答案，因为它很快就会过时。本文的目的是分析如何处理答案不能以期望的频率更新的情况。我们提出了解决这个问题的几种方法，并评估了它们的性能。
