Organization of mobile networks under privacy constraints

Abstract

In order to process requests for mobile computing environment, locations and requests from users have to be stored in the system. If these data are stored in one centralized system, it may be rather easy to get history of locations/requests of a specific user. Since it is not desirable to obtain such information by other users, we will introduce a system which will store such information in distributed way. User related information is stored in Information Kiosks. Users’ requests are sent to the central network by adding request ID without disclosing user ID. The central network is also allowed to broadcast information to be used by users. For practical reason we select hierarchical form for the network. How to process requests from users in such mobile systems is discussed. In order to get information not stored in the Kiosk nearby, we propose a system to form adhoc LAN among neighboring mobile terminals. The function can be used to realize applications using the real and virtual world together.
