Abstract
The increasing popularity of Multiplayer Online Games (MOGs) is revealing a huge interest from the research com- munity. Many solutions exploiting P2P technologies have been proposed in order to overtake the limits of the cen- tralized infrastructures. These solutions are based on the denition of a proper dynamic P2P overlay and exploit the concept of Area of Interest (AOI) to lter the information relevant for each player. An AOI-cast mechanism denes a spanning tree over the AOI so that the information gen- erated by a player is propagated to all the players located in its AOI. Although most proposals are founded on solid basis, they are often validated through players' movement patterns that result dierent form those of a real MOG. This paper presents a set of mobility models for the eval- uation of the AOI-cast. Together with classical mobility models, mobility patterns derived from popular MOGs, i.e. World of Warcraft(WoW) and Second Life(SL), are also pre- sented. A novel mobility mobility model taking into account the WoW battleground scenarios is proposed. The proposed mobility models are exploited to evaluate an AOI-cast algo- rithm based on the denition of a Delaunay overlay. The experiments show that the AOI-cast mechanism we propose can be exploited in real scenarios only when a set of condi- tions hold.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
