Massively Multiplayer Online Games (MMOGs) have gained a lot of popularity in recent years. The problem of defining a proper architecture supporting MMOGs is still a research challenge because the classical client server architecture mainly adopted in commercial applications presents several drawbacks like unsatisfactory scalability and limited fault tolerance. This paper presents HyVVE (Hybrid Voronoi...
This paper presents a novel Area Of Interest (AOI)‐cast algorithm for distributed virtual environments targeted to Delaunay‐based P2P overlays. The algorithm exploits the mathematical properties of Delaunay triangulations to build a spanning tree supporting the notification of the events generated by a peer to the other ones located in its AOI. The spanning tree is computed by the reversing compass routing...
This paper presents a AOI cast strategy for P2P Distributed Environments which is exploited to notify the position updates of a peer P, i.e. its heartbeats, to all the peers located in its Area of Interest. An algorithm for the construction of a spanning tree covering all the peers is presented. The algorithm exploits the properties of Delaunay Triangulations to reduce the traffic load on the P2P...
This paper presents an Area of Interest(AOI)-cast strategy for P2P Distributed Virtual Environment (DVE) which exploits a Delaunay Triangulation of the DVE to define a compass-based routing algorithm. A set of formal results for circular AOI is presented. Inconsistencies between local views of different peers due to the network latency are faced by introducing a tolerance threashold in the compass...
