Even though BitTorrent-like file sharing is successful for P2P (peer-to-peer) content-sharing over Internet, it suffers from the content unavailability problem when the contents are not popular (i.e., the absence of seed). This content unavailability can be mitigated by using multi-swarm cooperation and/or by bundling popular/unpopular contents. In this paper, by employing user-driven virtualized...
Today, Massive Multi-player Online Game (MMOG) has taken an important part in the field of entertainment. But its increasing requirement of resources has brought a heavy burden to the game server. To address this problem, we propose a Structured Multi-Agent (SMA) model which divides the resources into groups by the Area of Interest (AOI) and builds itself on the pastry protocol. Then, every other...
In this paper, a novel peer-to-peer (P2P) neighbor selection mechanism was proposed to enhance the efficiency of the file sharing process in P2P networks. In the mechanism, a modified and well-designed neighbor peer selection approach was introduced, which selects the neighbor peer based on the weighted value it holds. The weighted value includes several factors, such as the trust value, the number...
The peer-to-peer network has been widely used to share large files anonymously. Because of its open nature, nodes can join and leave peer-to-peer networks freely. But there are few limited methods to ensure their trust. Malicious nodes can expose great security threats to peer-to-peer networks such as spreading unauthentic data and viruses. But handling all the malicious nodes in the same way causes...
