Peer-to-peer (P2P) networking has emerged as a promising technology that enables distributed systems to operate in decentralized manner. P2P networks are based on model where each node the network can act both client and server, thereby enabling data resource sharing without relying centralized servers. The gained considerable attention recent years due its potential provide scalable, fault-tol...

The rapidly growing popularity of Massively Multiplayer Online Games (MMOGs) has given rise to an increase in the number of players world wide. MMOGs enable many players interact together through a shared sense of presence created by the game. The Peer-to-Peer (P2P) network topology overcomes communication bottleneck problems associated with centralized client/server systems. Thus, P2P-based MM...

With the progress of peer-to-peer technology, P2P applications have evolved and established themselves as the leading ‘growth app’ of Internet traffic workload. In order to reserve enough bandwidth for other applications, gateway of P2P systems must control P2P's traffic. In this paper, passive network measurement of P2P traffic is introduced, and network behaviors of some P2P applications are ...

Due to its ability to deliver scalable and fault-tolerant solutions, applications based on the peer-to-peer (P2P) paradigm are used by millions of users on the internet. Recently, wireless mesh networks (WMNs) have attracted a lot of interest from both academia and industry, because of their potential to provide flexible and alternative broadband wireless internet connectivity. However, due to ...

The popularity of video-on-demand (VoD) streaming has grown dramatically over the World Wide Web. Most users in VoD P2P networks have to wait a long time in order to access their requesting videos. Therefore, reducing waiting time to access videos is the main challenge for VoD P2P networks. In this paper, we propose a novel algorithm for caching video based on peers' priority and video's popula...

The unprecedented growth and increased importance of geographically distributed spatial data has created a strong need for efficient sharing of such data. Interestingly, the ever-increasing popularity of peer-to-peer (P2P) systems has opened exciting possibilities for such sharing. This motivates our investigation into spatial indexing in P2P systems. While much work has been done towards exped...

In order to define the problems we address in this thesis, this chapter reviews the state-of-the-art in P2P recommendation systems. First, we describe centralized recommendation systems, their approaches, and limitations. Second, we discuss P2P systems as an alternative, scalable solution for decentralized recommendation systems, and extract their requirements. Finally, we evaluate the existing...
