IEEE PerCom, now in its twelfth edition, is established as the premier annual scholarly venue in the areas of pervasive computing and communications. Pervasive computing and communications has evolved into an active area of research and development, due to the tremendous advances in a broad spectrum of technologies and topics including wireless networking, mobile and distributed computing, sensor systems, RFID technology, and the ubiquitous mobile phone. PerCom 2014 will be held in Budapest, the capital city of Hungary and one of the most idyllic and historic cities of Europe. PerCom 2014 will provide a leading edge, scholarly forum for researchers, engineers, and students alike to share their state-of-the art research and developmental work in the broad areas of pervasive computing and communications. The conference will feature a diverse mixture of interactive forums: core technical sessions of high quality cutting-edge research articles; targeted workshops on exciting topics; live demonstrations of pervasive computing in action; insightful keynote speeches; panel discussions from domain experts; and posters of emerging ideas. Research contributions are solicited in all areas pertinent to pervasive computing and communications, including: Innovative pervasive computing applications Data management for pervasive computing Programming paradigms for pervasive systems Architectures, protocols, and technologies for pervasive communications Software evolution and maintenance in pervasive systems Middleware for pervasive services and applications Adaptive, autonomic and context-aware computing Participatory and social sensing Opportunistic networking and sensing in pervasive systems Mobile/wearable computing systems and services in pervasive computing Energy-efficient and green pervasive computing Positioning and tracking technologies Sensors and RFID in pervasive systems Multimodal sensing and context for pervasive applications Machine learning for activity recognition Smart devices and intelligent environments Trust, security and privacy issues in pervasive systems User interface, interaction, and persuasion Context modeling and reasoning Cognitive computing in pervasive systems Virtual immersive communications Pervasive computing aspects of social networks Social and economic models for pervasive systems Workshops and Affiliated Events Many workshops will be held in conjunction with the main conference. Workshop papers will be included and indexed in the IEEE digital libraries (Xplore), showing their affiliation with IEEE PerCom. As in the past, PerCom 2014 will also feature a PhD Forum, Work-in-Progress Posters, and Live Demonstrations. Please visit the conference website for details. Submission Guidelines Submitted papers must be unpublished and not considered elsewhere for publication. Also, they must show a significant relevance to pervasive computing and networking. Only electronic submissions in PDF format will be considered. Papers must be 9 pages or less, including references, figures and tables (at least 10pt font, 2-column format). The IEEE LaTeX and Microsoft Word templates, as well as formatting instructions, can be found here. All papers will be managed electronically through the EDAS submission site. Submitted papers will undergo a rigorous review process handled by the Technical Program Committee. Additional author names cannot be added after acceptance. The best paper will receive the prestigious Mark Weiser Best Paper Award. Top selected papers will be considered for a special issue of the Elsevier journal of Pervasive and Mobile Computing (PMC).
