HotPOST'14

The 6th International Workshop on Hot Topics in Peer-to-peer computing and Online Social neTworking

Monday, June 30, 2014, Madrid, Spain

Held in conjunction with 34th IEEE ICDCS

Welcome!

Overview

The Sixth International Workshop on Hot Topics in Peer-to-peer computing and Online Social neTworking (HotPOST 2014) 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 We highly encourage novel and innovative previously unpublished work, even reporting work in early stage.


The workshop will be held in conjunction with IEEE ICDCS.


Important Dates
  • Submission deadline: 25th February, 2014 (extended)
  • Authors notification: 17th March, 2014
  • Camera-ready: 14th April, 2014
  • Workshop: 30th June, 2014



Call for Papers

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.


Papers accepted for HotPOST 2014 workshop will be published by the IEEE Computer Society Press. All accepted papers will be included in IEEE ICDCS 2014 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.

Topics of interest 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
  • P2P-based measurements
  • 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
  • P2P and OSN in information-centric networking

Submission Instructions

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 proceedings template 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.

The technical program committee will select one winner for the Best Paper Award and one winner for the Best Paper Runner-up.
Deadline for paper submission is 25th February, 2014 (extended).

Deadline for the submission is 14th April, 2014.

Keynote

Rade Stanojevic, Telefonica I+D, S.A.U., Spain

Title of the keynote: Quantifying the customer value in online services

Online services typically serve a wide range of customers with varying characteristics. Each customer has a unique pattern regarding when, what and how much services she accesses, who she interacts with, how much revenues she generates, etc. Engineering a successful online service requires a deep understanding of its customers in order to efficiently allocate the available resources. In this talk I will examine various dimensions that determine the value of an individual customer: from cost and service affinity to social influence. Using data from a cellular service provider I will demonstrate how user-profiling can help the provider to better manage its costs and revenues and ultimately increase its profitability. I will close by discussing possible directions on how user-centric design can benefit other online services such as online gaming or content delivery.



Rade Stanojevic obtained his B.Sc. in Mathematics from University of Nis, Serbia and a Ph.D. from Hamilton Institute, NUIM, Ireland. His current research interests span network economics and performance evaluation. His work on decentralized cloud control has been awarded the ACM SIGMETRICS 2008 Kenneth C. Sevcik Outstanding Student Paper Award and the IEEE IWQoS 2009 Best Paper Award. He was a staff researcher in the IMDEA Networks Institute, Madrid. He is a researcher of the Internet Scientific Group of Telefonica.
