Abstract:
In this paper we propose an efficient location management scheme for large amounts of mobile users and other objects in distributed, service-oriented systems. To efficiently observe geographic areas of interest (AOI) in command and control information systems (C2IS), i.e. to compute the AOI within a C2IS, we introduce the concept of region services. These services contain all objects of a fixed geographic region. To handle in-homogenous distributions of objects we propose a combination of regular and hierarchical regions. A user-specific C2IS instance can now directly and efficiently establish subscription-relations to the relevant objects around its AOI in order to obtain information about the position, status and behaviour of these objects. If objects including the current user itself now dynamically change their position we merely have to update the information relations to those few objects that enter or leave a region within the AOI, instead of having to consider all objects wit
hin the global information grid. Region services thus do not only improve the efficiency for generating a static common operational picture but can also handle any dynamic changes of object positions.
