Abstract
A key characteristic of mobile applications is the need for up-to-date location-dependent information, while physical locations change frequently. Recent improvements in wireless communication and hardware technology and Internet-based data exchange has created a new type of mobile application whose requirements are not met by traditional relational and object database systems. In this paper we describe MAGNET, a tuplespace-based framework for dynamic information storage and retrieval, addressing the needs of applications in frequently changing mobile environments, and discuss how this approach could enable flexible data exchange. In addition to type-free data storage and user-customized requests for data records, MAGNET enables adaptation to changing environments by supporting constant monitoring of selected information.
By ‘mobile users’ we mean weakly-connected (wireless) users frequently changing their location (e.g. ,taxi-drivers, tourists) typically using portable computers or PDAs.
A ‘mobile application’ we define as a distributed application run by mobile users (e.g., users with portables working while in transit, tourists while sightseeing, taxi-drivers etc. dealing with location-dependent information (e.g., a local resource, local ‘data’, a location-based request) in a changing environment.
