“…When the gathering event is dissolved it can be increased to its original size. Another way to decrease the load on the users is to vary the frequency of message exchange based on the distance within the AOI [9]. As this increases the response times, it is not suitable for a MMOFPS scenario.…”

We propose a design for massively multiplayer games with focus on fast-paced action. To reflect the high demands on responsiveness and scalability, we use a fully distributed peer-to-peer network with a dynamic connection scheme. While the capacity of current client/server systems limits the number of players in a game, our system supports a huge number of users by exploiting local interests in the virtual world. By using a publish/subscribe system for message dissemination user interests can be handled efficiently. A Geocast algorithm allows information distribution to arbitrary regions of the virtual world. Simulations show that our design scales well by limiting the number of connections per user even in crowded regions. Moreover, different movement strategies are evaluated for their impact on network load and connection dynamics.

Abstract-This paper presents a P 2P support for Massively Multiplayer On line Games. The P 2P overlay is defined by considering a Voronoi diagram where the sites correspond to the peers and a link connects Voronoi neigbours. 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. AOIcast has been evaluated through a set of simulations developed by Peersim.

“…Note that although we mainly discuss about the number of total users in the system (or system scalbility), and not the scalability of users within the AOI (or AOI scalability [9]), the two are directly related in our simulations as the world size is fixed (i.e., the increase in total number of users directly relates to an increase in user density). We can judge whether a system is scalable by considering its resource consumption.…”

In multi-user networked virtual environments such as Second Life, 3D streaming techniques have been used to progressively download and render 3D objects and terrain, so that a full download or prior installation is not necessary. As existing client-server architectures may not scale easily, 3D streaming based on peer-to-peer (P2P) delivery is recently proposed to allow users to acquire 3D content from other users instead of the server. However, discovering the peers who possess relevant data and have enough bandwidth to answer data requests is non-trivial. A naive query-response approach thus may be inefficient and could incur unnecessary latency and message overhead. In this paper, we propose a peer selection strategy for P2P-based 3D streaming, where peers exchange information on content availability incrementally with neighbors. Requestors can thus discover suppliers quickly and avoid time-consuming queries. A multi-level area of interest (AOI) request is also adopted to avoid request contention due to concentrated requests. Simulation results show that our strategies achieve better system scalability and streaming performance than a naive query-response approach.
