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 We highly encourage novel and innovative previously unpublished work, even reporting work in early stage.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).

The technical program committee will select one winner for the Best Paper Award and one winner for the Best Paper Runner-up.
