Online auctions are a platform to trade goods on the Internet. In this context, negotiation capabilities for software agents in continuous double auctions (CDAs) are a central concern. Agents need to be able to prepare bids for and evaluate offers on behalf of the users they represent with the aim of obtaining the maximum benefit for their users. For the agents, their bids are decided according to some bidding strategy. However, in CDAs, it is a complex decision problem because of the inherent uncertainty and dynamics of the auction market. In this book, we present a new bidding strategy for agents to adopt in CDAs and propose tools to enhance the performance of existing bidding strategies in CDAs. The superior performance of the new bidding strategy as well as the tools presented in this book are illustrated through extensive experiments.

Developments in optical transmission systems and electronic routers allow huge bandwidth and ever-increasing capacity. Yet the recent massive deployment of ADSL and broadband access, together with the outburst of new multimedia network services, have resulted in a significant increase in end-user traffic and bandwidth demands. This has motivated research into so-called "transparent optical networks", where the photonic technology is used not only for transmission purposes, but also for implementing more complex functions. This useful textbook/reference provides an overview of the key concepts related to the major issues of optical Internet, and studies traditionally and recently proposed optical switching paradigms. The concise, yet comprehensive coverage presents a detailed comparison of optical switching technologies, and covers architectural issues together with topics such as signaling protocols and Quality of Service (QoS) provision. Additionally, the book provides deep insight into recent advances in optical circuit switching, optical packet switching (OPS) and optical burst switching (OBS) technologies; their performance advantages, their control-plane specifications, their enabling technologies, their applicability in today's networks, and their cost benefits. Readers need only undergraduate background in computer communication networks on topics related to TCP/IP, SDH and MPLS networks. Topics and features: Provides a thorough overview of optical technologies and protocols for the Future Internet, presented by experts in the field from the e-Photon/ONe and BONE European Union Networks of Excellence Includes detailed examples, enabling readers to isolate similarities and performance differences Presents a thorough introduction to IP over Wavelength Division Multiplexing; describing SONET/SDH, ASON and GMPLS networks, and discussing the Routing and Wavelength Assignment problem Explores OPS, including header coding techniques and Fiber Delay Line buffers, as well as buffered switch architectures and Array Wave Grating space switching architectures Discusses topics relating to OBS, reviewing the issues of QoS provisioning in OBS and the interplay between Transmission Control Protocol and OBS Describes how an OBS network can support a ubiquitous Grid platform able to address the requirements of a large number of dynamic users Discusses implementation issues of optical switching fabrics and their applicability in the real world, presenting key performance indicators and describing applications such as Optical Cross Connects and Optical Add/Drop Multiplexers This wide-ranging and authoritative text will be a valuable resource for advanced undergraduates, beginning graduates, and researchers studying communications in either Engineering or Computer Science.

International Federation for Information Processing The IFIP series publishes state-of-the-art results in the sciences and technologies of information and communication. The scope of the series includes: foundations of computer science; software theory and practice; education; computer applications in technology; communication systems; systems modeling and optimization; information systems; computers and society; computer systems technology; security and protection in information processing systems; artificial intelligence; and human-computer interaction. Proceedings and post-proceedings of referred international conferences in computer science and interdisciplinary fields are featured. These results often precede journal publication and represent the most current research. The principal aim of the IFIP series is to encourage education and the dissemination and exchange of information about all aspects of computing. For more information about the 300 other books in the IFIP series, please visit www.springer.com. For more information about IFIP, please visit www.ifip.org.
