This book constitutes the proceedings of two conferences: The 6th International ICST Conference on Heterogeneous Networking for Quality, Reliability, Security and Robustness (QShine 2009) and the 3rd International ICST Workshop on Advanced Architectures and Algorithms for Internet DElivery and Applications (AAA-IDWEA 2009). QShine is a very successfull series of conferences providing an international forum for the discussion and sharing of new research ideas on the design and implementation of Quality of Service (QoS) in heterogeneous wireless and wireline networks. The 19 papers presented at the conference were selected from 40 paper submissions. In addition to this 25 papers from leading researchers working in related fields are presented. The conference is organized in 11 technical sessions covering IP telephony and multimedia, mesh networks, mobility and heterogeneous wireless networks. AAA-IDEA comprises 7 papers that cover a variety of topics such as architectures and algorithms for content and service delivery, energy-aware networks, QoE in media streaming as well as support for mobile and wireless systems.
