This book is a compilation of research accomplishments in the fields of modeling, simulation, and their applications, as presented at AsiaSim 2011 (Asia Simulation Conference 2011). The conference, held in Seoul, Korea, November 16-18, was organized by ASIASIM (Federation of Asian Simulation Societies), KSS (Korea Society for Simulation), CASS (Chinese Association for System Simulation), and JSST (Japan Society for Simulation Technology). AsiaSim 2011 provided a forum for scientists, academicians, and professionals from the Asia-Pacific region and other parts of the world to share their latest exciting research findings in modeling and simulation methodologies, techniques, and their tools and applications in military, communication network, industry, and general engineering problems.

This book constitutes the refereed proceedings of the EUC 2007 workshops held in conjunction with the IFIP International Conference on Embedded and Ubiquitous Computing, EUC 2007, in Taipei, Taiwan, in December 2007.

The 69 revised full papers presented together with 4 invited papers were carefully reviewed and selected from about 200 submissions to the seven workshops. Topics covered by the workshops are trustworthiness, reliability and services in ubiquitous and sensor networks (TRUST 2007), system and software for wireless system-on-chip (WSOC 2007), network centric ubiquitous systems (NCUS 2007), ubiquitous underwater acoustic-sensor network (UUWSN 2007), RFID and ubiquitous sensor networks (USN 2007), embedded software optimization (ESO 2007), and security in ubiquitous computing (SecUbiq 2007).
