The Phenomenon of Role Transition and Inertia in P2P System
This study is aim to investigate the transition and inertia phenomena of roles which users played in P2P systems. Some users tend to change their behaviors frequently (role transition), while others are more likely to keep one role over the time (role inertia). In P2P systems, users can download from others, and be downloaded by others freely if they are online. However, the patterns of download behaviors are very different from user to user. Some of them are more inclined to be free riders who just download from others but don’t let others download from them; some of them are more inclined to be altruist who just let others download from them but don’t download from others.
