Found in: 2012 IEEE 5th International Conference on Cloud Computing (CLOUD)
By Ulrich Lampe,Melanie Siebenhaar,Apostolos Papageorgiou,Dieter Schuller,Ralf Steinmetz
Issue Date:June 2012
pp. 83-90
Auctioning constitutes a market-driven scheme for the allocation of cloud-based computing capacities. It is practically applied today in the context of Infrastructure as a Service offers, specifically, virtual machines. However, the maximization of auction...
Enhancing the Caching of Web Service Responses on Wireless Clients
Found in: Web Services, IEEE International Conference on
By Apostolos Papageorgiou,Marius Schatke,Stefan Schulte,Ralf Steinmetz
Issue Date:July 2011
pp. 9-16
Contrary to simple Web content, standard Web services do not offer their clients the possibility to use cached information without the risk that it may be out-of-date. This feature has not been worth its costs in realistic Web service usage scenarios until...
Study and Comparison of Adaptation Mechanisms for Performance Enhancements of Mobile Web Service Consumption
Found in: Services, IEEE Congress on
By Apostolos Papageorgiou, Jeremias Blendin, André Miede, Julian Eckert, Ralf Steinmetz
Issue Date:July 2010
pp. 667-670
Mobile Web services lie on the intersection of two big IT trends, namely Service-oriented Architectures (SOA) and mobile applications. So, their usage is likely to expand dramatically in the next years. However, the heavyweight nature of service-orientatio...
Enhancing Availability with Self-Organization Extensions in a SOA Platform
Found in: Internet and Web Applications and Services, International Conference on
By Apostolos Papageorgiou, Tronje Krop, Sebastian Ahlfeld, Stefan Schulte, Julian Eckert, Ralf Steinmetz

As the principle of service-orientation is gaining ground in a significant number of emerging solutions, the definition of standards coupled with the appearance of new architectures bring a new era in software development. New technologies enable the usage...
A peer-to-peer environment for monitoring multiple wireless sensor networks
Found in: Proceedings of the 2nd ACM workshop on Performance monitoring and measurement of heterogeneous wireless and wired networks (PM2HW2N '07)
By Apostolos Papageorgiou
Issue Date:October 2007
pp. 132-135
In this work we present the basic concepts in the architecture of a peer-to-peer environment for monitoring multiple wireless sensor networks, called ShareSense. ShareSense, which is currently under development, uses JXTA as a peer-to-peer substrate. We de...
