This volume of the Lecture Notes in Computer Science series publishes the set of papers accepted for the ICQT 2006 workshop, i.e., the 5th International Workshop on Internet Charging and QoS Technology (ICQT), which was collocated with ACM SIGMETRICS. These events took place in St. Malo, France and were hosted by the IUT (Institut Universitaire Technologique) of St. Malo. QoS-guaranteed services enable a huge variety of prosperous business models, and the need for viable models and pricing schemes is urgent. The resulting combination of technical and economic perspectives drives many relevant research topics for application developers, business architects, network providers, service providers, and customers. Especially the identification of novel service charging solutions, the investigation and evaluation of their technical feasibility, and the consolidation of technical and economic mechanisms for enabling a fast, guaranteed, and efficient charging of services is of fundamental importance for the future evolution of the Internet, and as such the central focus of the international ICQT workshop series. This year's ICQT constituted the 5th vivid workshop on Internet economics and charging technology, which initially took place in 2001 in Vienna, Austria within the framework of the Annual Meeting of the German Society for Computer Science (GI) and the Austrian Computer Society, and which was collocated in 2002 with the QofIS 2002 workshop in Zurich, Switzerland, in 2003 with the NGC 2003 workshop in Munich, Germany, and in 2004 again with QofIS 2004 in Barcelona, Spain.

The 5th International Conference on Adhoc, Mobile and Wireless Networks (Adhoc-Now 2006) was held during August 17-19, 2006, in Ottawa, Canada. The ?rst four conferences in this series were held in Toronto (2002), Montreal (2003), Vancouver (2004) and Cancun (2005), respectively. The purpose of this conference is to provide a forum for researchers from academia/industry and practitioners to meet and exchange ideas regarding recent developments in the areas of ad hoc wireless networks. We received more than 170 papers for the conference submitted by authors from the following 25 countries: Australia, Bangladesh, Brazil, Canada, China, France, Germany, Greece, India, Iran, Ireland, Italy, Korea, Malaysia, Mexico, Nepal, Norway,Poland, Spain, Taiwan, The Netherlands, Turkey, UK, USA and Venezuela. Each paper was assignedto three members of the Technical Program Committee (TPC). Since each TPC member was responsible for generating - views for six to nine papers, we encouraged TPC members to delegate some reviews to other quali?ed reviewers. The names of all the TPC members and the additional reviewers appear elsewhere in this volume. Based on the reviews, we decided to accept 25 submissions as regular papers and 10 as short papers. Regular papers were given 25 minutes for presentation while short papers were given 15 minutes. All of the accepted papers appear in this volume. We are indebted to the TPC and the other reviewers for their detailed and timely reviews which enabled us to put together an excellent technical program.

The autonomic communication paradigm has been defined mainly through the Autonomic Communications Forum (ACF) and particularly as follows: Autonomic communication is centered on selfware - an innovative approach to perform known and emerging tasks of a network control plane, both end-to-end and middle box communication-based. Selfware assures the capacity to evolve; however, it requires generic network instrumentation. Selfware principles and technologies borrow largely from well-established research on distributed systems, fault tolerance among others, from emerging research on non-conventional networking (multihop ad hoc, sensor, peer-to-peer, group communication, etc. ), and from similar initiatives, such as Autonomic Computing of IBM, Cognitive Network of DARPA, Harmonious Computing of Hitachi, Resonant Networking of NTT, etc. A visionary network would be able to (a) configure and re-configure itself, (b) identify its operational state and take actions to drive itself to a desired stable state and finally (c) organize the allocation and distribution of its resources. To build such a network, it is necessary to go beyond the improvement of techniques and algorithms by using a new concept, the knowledge plane. The knowledge plane is able to collect information available in the network to provide other elements of the network with services and advice and make the network perform what it is supposed to. There are many objectives to the configuration and reconfiguration of the network, from the optimization of resources to the use of best available techniques in order to offer the most appropriate service, best adapted to the t- minal capabilities.

th This volume presents the proceedings of the 6 IEEE International Workshop on IP Operations and Management (IPOM 2006), which was held as part of Manweek 2006 rd th in Dublin, Ireland from October 23 to 25 , 2006. In line with its reputation as one ofthe pre-eminent venues for the discussion and debate of advances of management of IP networks and services, the 2006 iteration of IPOM brought together an international audience of researchers and practitioners from both industry and academia. The overall theme of Manweek 2006 was "e;Autonomic Component and System Management"e;,with IPOM taking this to be the application of autonomic principles to the IP operations, administration, maintenance and provisioning (OAM&P) domain. IPOM 2006 is more relevant than ever to the emerging communications infrastr- ture that is increasingly focused on "e;convergence"e; of networks and services. Although arguably over-hyped, there is a fundamental truth to this convergence story, and this is based on the fact that the TCP/IP protocol suite (IPv4 and IPv6) has become the common denominator for a plethora of such converged services. One good example in the period between IPOM 2005 and IPOM 2006 has been the large scale deployment of consumer VoIP, linked to the success of Skype and alternatives including SIP-based approaches. In many countries VoIP is driving broadband deployment for SMEs where real costs savings can be accrued, especially for companies with remote staff in the ?eld.

The optical networking field is seen to be rapidly emerging with a strong and s- tained technological and business growth. Research has led to massive development and deployment in the optical networking space leading to significant advancements in high speed network core and access networks. th The 11 International Conference on Optical Network Design and Modeling brought together scientists and researchers to meet and exchange ideas and recent work in this emerging area of networking. The conference was sponsored by IFIP and supported by the e-Photon/ONe and COST 291 projects. The conference proceedings have been published by Springer and are also available through the Springer digital library. The conference program f- tured 14 invited presentations and 41 contributed papers selected from over 90 s- missions. A series of sessions focusing on recent developments in optical networking and the related technology issues constituted the main conference program. The international workshop "e;Optical network perspectives vs. optical technologies th reality"e; was collocated with ONDM 2007 and took place on May 29 . It was org- ized by the EU COST 291 action. The objective of the workshop was to focus on cross layer issues and address various challenges with respect to the implementation of optical networking concepts based on available optical technology capabilities.

Globally, major network operators have incorporated network convergence into their strategy to grow service revenues and reduce capital and operating costs. Conv- gence occurs in applications (integrated messaging, voice over IP), in network control (portable numbers, SIP, mobile IP), in the transport layer, as well as in the access network. This convergence of networks means that various types of traffic flows, which have been carried by separate specialized networks, now share the resources of a single core IP-based network. In the access, the trends are towards fixed/wireless convergence as well as convergence of various wireless access technologies. Network convergence will be successful only if the quality of the individual s- vices is maintained in the new network environment without undue increased costs. The quality of service delivery is critically dependent on how network performance and availability, as experienced by the traffic flows, are managed. Managing traffic performance is a critical enabler for success. Reaching the desired performance levels requires adapting processes such as network planning, resource engineering, and network monitoring to the converged network milieu.

You hold in your hands the proceedings of ESAS 2007, the Fourth European Workshop on Security and Privacy in Ad hoc and Sensor Networks. The wo- nd rd shop took place in Cambridge, UK, on the 2 and 3 of July 2007. The workshop was European in name and location but it was de?nitely transatlantic in scope. We had a program chair from Europe and one from the USA, and membership of our program committee was almost evenly split - tween those two regions. When looking at participation, the workshop was even more global than that: the submitted papers came from 25 countries in 6 con- nents. We received 87 submissions. After quick-rejecting 5 papers deemed to be out of scope, the remaining 82 papers were each reviewed by at least three PC members. The two program chairs, who did not submit any works, had sole authoritytodecidewhichpaperstoacceptandreject,basedonlyonthedirective that quality had to be the primary criterion, in order to form a proceedings volume of high international relevance. The number of papers to be accepted was not set in advance: it was selected a posteriori so as to include only solid, innovative and insightful papers. The resulting acceptance rate of about 20%, very strict for a workshop, is a testimonial of how selective we chose to be in accepting only high quality papers.

This book constitutes the refereed proceedings of the Second International Workshop on Self-Organizing Systems, IWSOS 2007. The 17 revised full papers and five revised short papers presented together with two invited talks were carefully selected from more than 36 submissions. The papers are organized in topical sections on ad hoc routing, peer-to-peer networking, network topology, adaptive and self-organizing networks and multicast and mobility protocols.

Mobile Response 2008, the Second International Workshop on Mobile Infor- tion Technology for Emergency Response, aimed at a focussed exchange on how mobile information technology can be e?ectively used to the bene?t of em- gency response. The gap between the great potential bene?t that usable mobile IT could yield in the domain of emergency response and the speci?c design challenges for such technologies in this particularly unforgiving domain was the foundation of our decision to create a venue for researchers and practitioners from di?erent disciplines. During this year's workshopthe latest approachesand technical solutions in the area of mobile information technology for emergency response planning and execution were presented and demonstrated. We invited participation from research, industry and public rescue orga- zations to enable an in-depth discussion of the opportunities and drawbacks of new digital technologies for emergency response. The call for papers for the second Mobile Response workshop attracted over 25 submissions from 11 d- ferent countries, including international submissions from the USA, Brazil and Japan.AninternationalProgramCommitteewithexpertsonmobileinformation technology, emergency response and emergency response equipment selected 12 submissions for presentation during the workshop. The program was completed by two outstanding keynote presentations and one invited presentation on p- vailing topics of high interest to the scienti?c and practitioner communities.

On behalf of the IEEE Communications Society, the Technical Committee on Network Operations and Management (CNOM), the Manweek 2007 Organizing Committee, and the members of the IPOM Technical Program Committee, it is our pleasure to present the proceedings of the Seventh IEEE Workshop on IP Operations and Management (IPOM2007), held as part of Manweek 2007 during October 31-November 2, 2007. With the widespread deployment of IP-based networks, their operations and management have become increasingly important in terms of understanding emerging technical and scientific problems; lessons from such understanding are particularly important for future Internet design and management. Like the previous IPOM workshops, IPOM 2007 was co-located with several related events as part of the 3rd International Week on Management of Networks and Services (Manweek 2007). The other events were the 10th IFIP/IEEE International Conference on Management of Multimedia and Mobile Networks and Services (MMNS 2007), the 18th IFIP/IEEE International Workshop on Distributed Systems: Operations and Management (DSOM 2007), the 2ndIEEE International Workshop on Modeling Autonomic Communications Environments (MACE 2007), and the 1st IEEE/IFIP International Workshop on End-to-End Virtualization and Grid Management (EVGM 2007). Co-locating those events provided the opportunity for an exchange of ideas between research communities that work on related topics, allowing participants to forge links and exploit synergies.

The 3rd Asian Internet Engineering Conference (AINTEC) followed the ?rst two successful editions held in Bangkok, Thailand, and focused on developing synergies between researchers in Asia and worldwide, but was also a unique chanceforyoung,talentedregionalscientiststomeetandinteract.AINTEC2007 wasthereforeamajoropportunityforpresentationsanddiscussionsaroundthese objectives. In particular, it aimed at addressing issues pertinent to the Asian region with vast diversities of socio-economic and networking conditions while inviting high-quality and recent research results from the global international research community to be presented. The conference is single-track to favor discussions among a diverse set of participants. We want to thank the authors of the 66 papers submitted for considering AINTEC as the right target for their paper. The submissions came from 18 countries with, as expected, a majority from Asia. The program was composed of 14 accepted papers organized in 6 technical sessions including 7 invited talks by leading experts on innovative topics, presentations of papers, demos, posters and a pre-conference18th Asian School on Computer Science (November, 25-26 2007). You might think that AINTEC is yet another conference but it has di?erent objectives and spirit, it o?ers a great opportunity to discuss future challenges for a sustainable Internet, and to get to know the local and regional researchers and enjoy the great hospitality of Thailand.

The advent of the Internet has opened up a wealth of applications, but also given rise to a host of new problems. Many of those problems have led to - citing new research directions in mathematics and theoretical computer science, especially in the areas of combinatorics and algorithms. The Fourth Workshop on Combinatorial and Algorithmic Aspects of Networking (CAAN 2007) was organized to be a place where the latest research developments on all aspects of networking could be presented. The topics covered were diverse, with talks on strategies for searching in networks, for cleaning networks of unwanted - truders, on di?erent routing strategies, and on scheduling and load balancing. The workshop started with an invited lecture by Peter Winkler of Dartmouth College, who gave a general talk on a topic related to probability, a concept central to network modeling and managing. The afternoon opened with a short invited talk by Alejandro Lop ' ez-Ortiz, who gave an overview of various issues in designing resilient backbone networks. CAAN 2007 took place on August 14, 2007, at Dalhousie University in Halifax, Nova Scotia, Canada, co-located with the Workshop on Algorithms and Data Structures (WADS 2007). Three previous CAAN workshops were held in Chester, UK (CAAN 2006), Waterloo, Ontario, Canada (CAAN 2005), and in Ban?, Alberta, Canada (CAAN 2004), respectively.

The book constitutes the refereed proceedings of the Fifth International Conference on Distributed Computing in Sensor Systems, DCOSS 2009, held in Marina del Rey, CA, USA, in June 2009. The 26 revised full papers presented were carefully reviewed and selected from 116 submissions. The research contributions in this proceedings span many aspects of sensor systems, including energy efficient mechanisms, tracking and surveillance, activity recognition, simulation, query optimization, network coding, localization, application development, data and code dissemination.

The Grid computing concept, which allows users to integrate administratively and g- graphically dispersed computing resources, has been gaining traction in a number of application areas during the past few years. By interconnecting many - heterogeneous, though usually virtualized - computing resources, virtual computer centers or superc- puters can be created, providing a seamless supply of computing resources. Grid comp- ing provides benefits not only for scientific computing (e.g., SETI@home, which interconnects one million computers across 226 countries with a total processing power of 711 TFLOPS) but also in a commercial environment. It is projected that computing Grids can lower the total IT costs of businesses by 30%. The report "e;Grid Computing: A Vertical Market Perspective 2005-2010"e; (by The Insight Research Corporation) estimates an increase of worldwide Grid spending from $714.9 million in 2005 to approximately $19.2 billion in 2010. One of the most prominent activities in academia is the EGEE project being funded with 30 MEuro by the European Commission. EGEE brings together researchers from over 27 countries with the common aim of developing a service Grid infrastructure, which is suited for scientific computing with very high demand for processing power.
