In current distributed systems, the notion of mobility is emerging in many forms and applications. Mobility arises naturally in wireless computing sin ce the location of users changes as they move. Besides mobility in wireless computing, software mobile agents are another popular form of moving objec ts. Locating objects, i.e., identifying their current location, is central to mobile computing. In this paper, we present a comprehensive survey of th e various approaches to the problem of storing, querying, and updating the location of objects in mobile computing. The fundamental techniques underly ing the proposed approaches are identified, analyzed, and classified along various dimensions.
