Location Management Using Hierarchical Structured Agents for Distributed Databases

Location-based services (LBS) depend on data gathered from mobile and ubiquitous devices and provide services like getting the appropriate location of a mobile user presented in physical and logical maps. The main operations of location management in LBS are update and search methods. Some studies to improve these were presented by using optimal sequential paging, location area scheme and hierarchical database scheme. In addition, not all LBS have the same access methods on data and they lead to difficulties of providing services. In this paper, we use an approach of hierarchical structured agents for locating a mobile object in a location-based service. This research focuses on location management by using agents. The agents are used for accessing distributed databases on LBS. It also introduces a hierarchical search method that uses a nearest neighbor technique for efficient search. The result of using the technique shows an improved search method in the location management.
