Peer-to-peer (P2P) systems are widely used in today's Internet and produce a 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. By attracting more than half a billion users worldwide, online social networks (OSNs) provide 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 OSNs from privacy violations.

The Fifth International Workshop on Hot Topics in Peer-to-peer computing and Online Social neTworking (HotPOST'13) is organized with the objective of bringing together researchers working on the intersection of P2P and OSN 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 We highly encourage novel and innovative previously unpublished work, even reporting work in early stage.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
- Large scale content distribution
- 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
- Location-based services in OSNs

Papers accepted for HotPOST 2013 workshop will be published by the IEEE Computer Society Press. All accepted papers will be included in IEEE ICDCS 2013 workshop proceedings, as well as IEEE Xplore (indexed by EI).

Authors are encouraged to submit full papers describing original, previously unpublished, complete research, not currently under review by another conference or journal, addressing state-of-the-art research and development in all areas of P2P/OSN.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 EasyChair. Papers should be submitted as PDF files, using the IEEE Computer Society proceedings or equivalent format (two column, 10 point, single-spaced, US Letter, no margin smaller than one inch). The maximum size of papers should be 6 pages including tables and figures with up to 1 over-length page. Extra page charge is $150. 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.
