A Collaborative Infrastructure for Mobile and Wireless Systemsork neutral format like XML. To turn collaboration spaces into a business model, however, research communities from fields like databases, document processing, groupware, interface design and mobile communication must join their efforts.

Prospects of Secure Real-Time Video Transmission over CDPD Networksion and bilateral authentication technique based on X.509 certificate between the mobile units and base stations. The overhead traffic resulting from the additional encryption and authentication layer is one of the major challenges for secure real-time video transmission over CDPD.

Flexible Integrated Cache for Efficient Information Access in Mobile Computing Environmentsfor cache space. The weight of an item in the cache is determined by several network specific and user defined parameters. A dynamic programming technique is employed to determine the optimal set of cache items. Such an optimized cache increases hit ratio and thereby reduces the strain on the wireless link and enhances QoS provisioning.

Design Considerations for Mobile Client-Server Database Applicationsreal estate, financial advising, and insurance. We take up the issues of synchronization performance and scalability, and describe the impact of mobility on server, network, and client design. A survey of relevant research is used to motivate our discussion.

The Rationale for Infrastructure Support for Adaptive and Context-aware Applications: A Position Papver, there are no standards (or even accepted best practices) for coordinating adaptation across multiple applications and systems. In this position paper we argue that the lack of standards in this area will inhibit the widespread deployment of many of the compelling context-aware mobile applications currently being designed.

Mobile Wireless Interfaces: In Search for the Limitsogies for porting information and functionality from traditional PCs to mobile devices and vice versa. We argue that in order to be able to properly port things between devices an equivalence concept for user interfaces is required.

Middleware for Location Based Information Services in Mobile Environmentmponent-based Middleware. The LBIS system resolves many issues in mobile and distributed environments, such as scalability, heterogeneity, reliability, and adaptability. Here we describe the detailed system architecture and implementation of the LBIS system and evaluate the system.
