Welcome to participate in the 11th International Conference on Embedded and Ubiquitous Computing (EUC-13), Zhangjiajie, China, November 13-15, 2013! Zhangjiajie is a rising tourist city famous for its unique natural scenery and abundant tourism resources. It is located in the northwest of Hunan province, about 400 kilometers away from Changsha, the capital of Hunan province, covering a total area of 9,563 square kilometers, of which 76% are mountainous area. Out of its total population of 1.62 million, almost 72% belong to ethnic minority groups, including Tujia, Bai and Miao nationalities. Zhangjiajie was listed into the World Natural Heritage Catalogue by the UNESCO in 1992. Zhangjiajie was awarded the title of “World Geological Park” in 2004. Embedded and ubiquitous computing is an exciting paradigm that promises to provide computing and communication services to the end users all the time and everywhere. Its systems are now invading in every aspect of our daily life and promise to revolutionize our life much more profoundly than elevators, electric motors or even personal computer evolution ever did. The emergence of this technology is a natural outcome of research and technological advances in a variety of areas including embedded systems, pervasive computing and communications, wireless networks, mobile computing, distributed computing and agent technologies. EUC 2013 is the next event, in a series of highly successful International Conferences on Embedded and Ubiquitous Computing (EUC), previously held as ICDCS-ECS04 (Tokyo, Japan, March 2004), EUC-04 (Aizu, Japan, August 2004), EUC-05 (Nagasaki, Japan, December 2005), EUC-06 (Seoul, Korea, August 2006), EUC-07 (Taipei, Taiwan, December 2007), EUC-08 (Shanghai, China, December 2008), EUC-09 (Vancouver, Canada, August 2009), EUC-10 (Hong Kong,China, December 2010), EUC-11 (Melbourne, Australia, October 2011) and EUC-12 (Paphos, Cyprus, December 2012).
