As software systems become increasingly ubiquitous, issues of dependability become ever more crucial. The 13 papers are organized in topical sections on: mobile and ubiquitous systems, architecting systems, fault management, and experience and vision.

1. Mobile and Ubiquitous Systems.- Self-healing for Pervasive Computing Systems.- Self Organization and Self Maintenance of Mobile Ad Hoc Networks through Dynamic Topology Control.- Data Backup for Mobile Nodes: A Cooperative Middleware and an Experimentation Platform.- 2. Architecting Systems.- Identification of Security Requirements in Systems of Systems by Functional Security Analysis.- Implementing Reliability: The Interaction of Requirements, Tactics and Architecture Patterns.- A Framework for Flexible and Dependable Service-Oriented Embedded Systems.- Architecting Robustness and Timeliness in a New Generation of Aerospace Systems.- 3. Fault Management.- Architecting Dependable Systems with Proactive Fault Management.- ASDF: An Automated, Online Framework for Diagnosing Performance Problems.- 4. Experience and Vision.- Is Collaborative QoS the Solution to the SOA Dependability Dilemma?.- Software Assumptions Failure Tolerance: Role, Strategies, and Visions.- Architecting Dependable Systems Using Reflective Computing: Lessons Learnt and Some Challenges.- Architecting and Validating Dependable Systems: Experiences and Visions.
