AOI-Cast Strategies for P2P Massively Multiplayer Online Games

This paper presents a P2P support for massively multiplayer on line games. The P2P overlay is defined by considering a Voronoi diagram where the sites correspond to the peers and a link connects Voronoi neighbors. An AOI-cast mechanism is defined to notify events generated by a peer to peers located in its area of interest. A routing algorithm exploiting the properties of the Voronoi graph has been defined as well. AOI-cast has been evaluated through a set of simulations developed by Peersim.
