P2P Technologies for Emerging Wide-Area Collaborative Services and Applications
Related to the COPS workshop, there is an open call for a Special Issue on the Elsevier Computer Networks Journal. COPS selected papers will be invited to send extended versions to this Special Issue. Furthemore, we invite all authors to send high quality papers.
Summary
With the rapid proliferation of popular collaborative applications such as Flickr, Wikipedia, and Facebook, to name a few, collaboration has become part of our daily life. These applications have shown how powerful collaboration can be, leading to a new interconnected and collaborative world. Another example of collaboration is the Large Hadron Collider (LHC) project. This project involves collaborators from more than 100 countries, many of whom may never meet in person, with the sole intention of verifying various hypotheses on high-energy physics. In general, wide-area collaboration is essential for any application designed to help people around the globe to work collaboratively on a common task.
Currently, collaborative applications commonly use centralized architectures that, in practice, do not necessarily scale. For example, Wikipedia receives more than 50 millions page requests per day, which has required spending thousands of dollars to fund an infrastructure able to handle such an intense load. To overcome this limitation, it has been argued that Peer-to-Peer (P2P) technology could provide the necessary substrate to boost collaboration in the Internet.
However, achieving the same functionality of centralized architectures on a fully decentralized system poses numerous challenges. For example, important difficulties arise from selfish peers, also known as "free riders", who wish to benefit themselves of the network resources while contributing little or nothing in return. Another example is how to manage the collaborative data. Is it accessible by all users or only by editors? Is it editable by more than one user simultaneously? In general, controlling and keeping track of concurrent changes, providing keyword search functionality and tracking the version of each document are complex questions that require sophisticated algorithms.
Other problems are related to the form of enacting collaborative processes. Peers can fail or act maliciously, and therefore, a collaborative P2P system should be robust against failures. The situation becomes even more challenging when we consider the heterogeneity of peers. Peers vary tremendously in their processing capabilities, connection times, and available bandwidth. How to exploit heterogeneity to improve the performance of the whole system is also an open problem. All these questions need answers before collaborative applications such as Wikipedia can be redeployed over P2P networks.
Finally, Social Networks represent a challenging substrate for collaborative P2P systems. In this line, social networks can be employed as computing and communication substrates in p2p collaborative settings. In such environments, the social connectivity is just another variable to tackle --- like network connectivity or resource availability. Furthermore, P2P platforms can be used to discover users and information, to aggregate community contents or even as a communication medium for large groups.
The goal of this special issue is to publish state-of-the-art approaches and technical solutions in the area of P2P technologies for emerging wide-area collaborative services. The issue will provide a convincing forum for researchers and practitioners to present their latest research results.
