* HotPOST 2011 is endorsed by European Alliance for Innovation.

Peer-to-peer (P2P) systems and applications are widely used in today's Internet and produce the most significant portion of its traffic. The increasing penetration of wireless technologies, the popularity of mobile and handheld devices, and the rapid growth of their user base call for innovative algorithms, protocols, and applications that benefit from infrastructure-less P2P technologies to support ever-increasing demand.

Following the success of the predecessor of HotPOST; P2PNet'09 in St.-Petersburg and P2PNet'10 in Shanghai, this year's event further expands its scope to include online social networks (OSNs) as well. By attracting more than half a billion users worldwide, OSNs are a new venue of innovation with many challenging and practical research problems. In particular, more and more P2P applications involve social information to enhance the user experience. Also, P2P based solutions play an important role in preventing OSN from privacy violations.

This workshop is organized with the objective of bringing together researchers working on the intersection of both topics to present and discuss their latest research results and ideas, thereby promoting the development and evolution of this area. All submissions on P2P and OSN related to architecture, design, implementation, simulation, analysis and measurement are welcomed. We highly encourage novel and innovative previously unpublished work, even reporting work in early stage.

Topics include but are not limited to:

Social network analysis for P2P and distributed computing systems
OSN-based systems and designs
P2P-based social networking architectures
P2P-based solutions to cloud computing and data center problems
Evolution of P2P communities and systems
Reputation, security, incentives, and economics in P2P systems
Mobile P2P and social networking systems
P2P overlays, file sharing, and streaming systems
User behavior analysis and modeling in OSNs
Security and privacy in OSNs
Evolutions and dynamics of OSNs and their implications
Decentralized OSN Applications
Social graph analysis

Papers accepted for HotPOST 2011 workshop will be published by the IEEE Computer Society Press. All accepted papers will be included in IEEE Xplore and indexed by EI. The technical program committee will select one winner for the Best Paper Award and two winners for the Best Paper Runner-up.

Paper submission: September 7, 2011 (Firm Deadline).
Acceptance notification: September 30, 2011.
Author registration: October 7, 2011.
Camera ready: October 14, 2011.

Authors are encouraged to submit full papers describing original, previously unpublished, complete research, not currently under review by another conference or journal, addressing state-of-the-art research and development in all areas of P2P/OSN. Papers must be submitted electronically in the EasyChair (https://www.easychair.org/conferences/?conf=hotpost2011). The maximum size of papers should be 6 pages including tables and figures. The cover page must contain an abstract of about 150 words, 3-5 keywords, name and affiliation of author(s) as well as the corresponding author's e-mail and postal address. Each submission will receive at least three independent blind reviews from the TPC. At least one of the authors of every accepted paper must register and present their work at the workshop.
