The advances in wireless communication technologies and the proliferation of mobile devices have enabled the realization of intelligent environments for people to communicate with each other, interact with information-processing devices, and receive a wide range of mobile wireless services through various types of networks and systems everywhere, anytime. A key enabler of this pervasive and ubiquitous connectivity environment is the advancement of software technology in various communication sectors, ranging from communication middleware and operating systems to networking protocols and applications.The 2010 edition of MOBILWARE will be the first time to move out of Europe. We plan to further diversify the representation of key organizers and expand the community of industrial and academic researchers fruitfully exchanging novel ideas and operational experiences in the field. MOBILWARE is dedicated to addressing emerging topics and challenges in various mobile wireless software-related areas. The scope of the conference is the design, implementation, deployment, and evaluation of middleware, operating systems, and applications for computing and communications in mobile wireless systems. It aims to provide a high profile, leading edge forum for researchers, engineers, and standards developers to present their latest research activities, techniques, and experiences in the area of software technology for mobile wireless systems.
