A Survey of Socially Aware Peer-to-Peer Systems
Xiang Zuo, Adriana Iamnitchi · ACM Computing Surveys · 2016
Peer-to-peer technologies have proven their strength in large-scale resource sharing and data transfer. Such systems, however, still need to address a variety of issues, including efficient routing, security, quality of service, incentives, and reputation. Recent research started leveraging social information to develop new and effective techniques to improve the performance of peer-to-peer systems. However, using social information is a double-edged sword, which can bring benefits as well as new challenges. This survey presents and classifies the types of social information that have been used so far in the design of peer-to-peer systems, how the social fabric has been used to facilitate transactions in the system, and some challenges caused by using social information.
