Develo** an Infrastructure for Mobile and Wireless Systems
NSF Workshop IMWS 2001 Scottsdale, AZ, October 15, 2001 Revised Papers
Chapter and Conference Paper
We propose an agent architecture that provides transparent access to a set of distributed, heterogeneous, and autonomous information sources. Our objectives are twofold: First, we want to support quick develop...
Chapter and Conference Paper
Mediator architectures have become popular for systems that aim at providing transparent access to heterogeneous information sources. Similar to a view on a database, a mediator answers queries posed against t...
Chapter and Conference Paper
One major problem with the use of mediator-based architectures is long query response times. An approach to shortening response times is to cache data at the mediator site. Recently, there has been growing int...

Chapter and Conference Paper
One of the core functionalities needed in ad-hoc peer-to-peer networks is service discovery. However, none of the existing solutions for service discovery work well in these dynamic, decentralized environments...
Chapter and Conference Paper
The recent NSF Workshop on Infrastructure for Mobile and Wireless Systems, held on Oct. 15, 2001 in Phoenix had a goal of defining and establishing a common infrastructure for the discipline of mobile wireless...
Chapter and Conference Paper
In distributed environments, collaboration is often achieved with the help of services. To enable automatic service trading, semantically expressive, automatically comparable, flexible, and editable service de...
Chapter and Conference Paper
In order for service-oriented architectures to become successful, powerful mechanisms are needed that allow service requestors to find service offerers that are able to provide the services they need. Typicall...
Chapter and Conference Paper
Matching of semantic service descriptions is the key to automatic service discovery and binding. Existing approaches split the matchmaking process in two step: signature and specification matching. However, th...
Chapter and Conference Paper
Wireless network research still lacks methods to integratively evaluate the performance that can be expected from application layer protocols. The user behavior is predominantly affecting network performance a...
Chapter and Conference Paper
The wide availability of mobile devices equipped with wireless communication capabilities results in highly dynamic communities of mobile users. An interesting application in such an environment is decentraliz...
Chapter and Conference Paper
In ad hoc networks, devices have to cooperate in order to compensate for the absence of infrastructure. Yet, autonomous devices tend to abstain from cooperation in order to save their own resources. Incentive ...
Chapter and Conference Paper
Distributed reputation systems are a self-organizing means of supporting trusting decisions. In general, the robustness of distributed reputation systems to misbehavior is evaluated by the means of computer ba...
Chapter and Conference Paper
Autonomous entities in artificial societies are only willing to cooperate with entities they trust. Reputation systems keep track of the entities’ behavior and, thus, are a widely used means to support trust f...

Wireless network research still lacks methods to evaluate the performance that can be expected from application layer protocols. User behavior is the predominant factor affecting network performance on this la...
Chapter and Conference Paper
The area of service oriented computing stretches between two extremes: On the one hand industry has pushed a whole stack of WS-* standards and tools to support the integration of distributed services into busi...
Chapter and Conference Paper
In realistic settings, service descriptions will never be precise reflections of the services really offered. An online seller of notebooks, for instance, will most certainly not describe each and every notebo...
Chapter and Conference Paper
Today, Portals provide users with a central point of access to companywide information. Initially they focused on presenting the most valuable and widely used information to users for efficient information acc...
Chapter and Conference Paper
Modern Web 2.0 Portals have become highly collaborative participation platforms. Users do not only retrieve information, they even contribute content. Due to the large number of different users contributing, W...
Chapter
In recent years a huge amount of effort, and money has been invested in the area of semantic service discovery and presented approaches have become more sophisticated and mature. Nevertheless surprisingly litt...
