CALL FOR PAPERS IEEE PerCom, now in its 11th edition, has established itself 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 2013 will be held in San Diego, \"America\'s finest city,\" famous for its climate, beaches, and numerous tourist attractions. PerCom 2013 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 budding ideas. Research contributions are solicited in all areas pertinent to pervasive computing and communications, including: Innovative pervasive computing applications Context modeling and reasoning Data management for pervasive computing Programming paradigms for pervasive systems Software evolution and maintenance in pervasive systems Middleware for pervasive services and applications Adaptive, autonomic and context-aware computing Mobile/wearable computing systems and services in pervasive computing Energy-efficient and green pervasive computing Communication architectures for pervasive computing Ad hoc networks for pervasive communications Pervasive opportunistic communications and applications Enabling technologies for pervasive systems (e.g., wireless BAN, PAN) Positioning and tracking technologies Sensors and RFIDs in pervasive systems Multimodal sensing and context for pervasive applications Participatory, opportunistic and social sensing Smart devices and intelligent environments Trust, security and privacy issues in pervasive systems User interface, interaction, and persuasion 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 2013 will also feature a PhD Forum, Demonstrations, and a Work-in-Progress Session. Submission Guidelines: Submitted papers must be unpublished and not considered elsewhere for publication. They must show 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 manuscripts must be registered and submitted electronically through the EDAS submission site. Submissions will undergo a rigorous review process handled by the Technical Pro-gram Committee. 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) For additional information contact the PerCom 2013 organizing committee at percom2013@dico.unimi.it.
