The focus in development methodologies of large and complex software systems has switched in the last two decades from functional issues to structural issues; this holds for both the object-oriented and the more recent component-based software engineering paradigms. Formal methods have been applied successfully to the verification of medium-sized programs in protocol and hardware design for quite a long time. However, their application to the development of large systems requires more emphasis on specification, modeling and validation techniques supporting the concepts of reusability and modifiability, and their implementation in new extensions of existing programming languages like Java. This state-of-the-art survey presents the outcome of the 9th S...

This book constitutes the proceedings of the First International ICST Conference, MOBILIGHT 2009 held in Athens, Greece in May 2009. The 40 full papers presented focus on topics such as WPAN, WLAN, WMAN/cellular as well as architectures and design methodologies to support seamless access to the comunication facility. Further contents are services, in the vison of "always on" requirements as well as business models, oportunities and solutions. This volume reflects the current request for lighweight, wireless communication devices with high usability and performance able to support added-value service in a highly mobile environment....
