Network game design

Kuan-Ta Chen, Chin-Laung Lei
2006 Proceedings of 5th ACM SIGCOMM workshop on Network and system support for games - NetGames '06  
While psychologists analyze network game-playing behavior in terms of players' social interaction and experience, understanding user behavior is equally important to network researchers, because how users  ...  We also find that participants who have a higher degree of social interaction tend to play much longer, and players who are closer in network topology tend to team up for longer periods.  ...  Currently, there are three common approaches for constructing overlay networks: 1) numeric-ID based [7] ; 2) network topologybased [6] , e.g., optimizing network latency; and 3) in-game location-based  ...
