Location management refers to the problem of updating and searching the current locations of multiple mobile nodes in a wireless network. To make location management efficient, the sum of update and lookup costs of the location database must be minimized. The authors of this paper hypothesize that previously proposed location management techniques rely on fixed location databases, and are therefore unable to fully exploit the knowledge of user mobility patterns in the system so as to achieve this minimization. This paper presents a novel location management architecture that has the ability to react dynamically to user pattern changes by having mobile location databases.
