Research on Service Matching Method for LBS

Abstract

With the development of mobile computing, location-based service (LBS) is becoming an important aspect of applied research, the technology of service discovery becomes a core issue. So service matching is the most important in service discovery, also it became hot spot in researching. In the process of providing service to user, not only the quality of service should be improved, but also user’s preferences should be considered. The existing mainstream service discovery protocols in the location-oriented service were compared in this paper. Based on analysis and comparison, a new algorithm of service matching is proposed in this paper. It improves the service matching success rate through hierarchical matching and full accounting of the user’s preference, and ultimately aim to improve service quality.
