Nowadays, MMOGs are extensively used as they provide the ability for centralized gaming with many players. MMOGs can be classified into three different categories: MMRPOG that are role games, MMORTS based on real-time strategy games and MMOFPS named as first person shooter games. The computational requirements of these categories are different. In this paper we focus on MMOFPS, whose main gaming requirements are low latency values and scalability. We propose a new system called OnDeGaS (On Demand Game Service), that combines the functionalities of a centralized server infrastructure with a distributed P2P topology, in such a way that the system can grow at any moment according to the existing demand, by maintaining QoS. We evaluate the effectiveness of the OnDeGaS through simulation. The results show that the system is able to scale, while the average latency of the whole system is always maintained under an acceptable threshold. We also probe the benefits provided by the fault tolerance mechanism included in the system.
