course description
Course Description

This course provides an in-depth examination of advanced topics in peer-to-peer (P2P) networking in which all the peers play symmetric roles as both clients and servers.

course description1
Course Description
  • The course has two parts:
    • The first part covers traditional P2P-related topics such as P2P data sharing, P2P resource search, P2P storage, P2P multicast, P2P security, P2P reputation and incentive, P2P censorship-resistance, P2P resource trading, P2P knowledge sharing, P2P on mobile ad hoc networks, and so on.
course description2
Course Description
  • The course has two parts:
    • The second part covers P2P networked virtual environment (P2P NVE) related topics, such as P2P massively multiplayer online games (MMOGs), latency compensation, playability, cheats, community management and 3D scene streaming for online games, etc.
course description3
Course Description

We may add some topics about P2P OSNs (Online Social Networks) in 2011

After learning the course, the students can become familiar with basic concepts of P2P networking related topics.

  • Many nodes on a 2D plane
  • An avatar needs to know only those within Area of Interest (AOI)‏
