Peer-to-peer (P2P) applications have shown their popularity in the Internet, while become a burden of Internet Service Providers (ISPs) because they produce huge traffic on network. The enormous traffic comes from the fact that when P2P systems construct overlay networks, they ignore the underlying network topology, so most of the connections are between remote peers and cross different networks....
In this paper, we investigate the mobile P2P file-sharing problem, and proposed a mobile P2P content distribution architecture. Due to mobile specific influence factors, a hybrid architecture has been employed. We assume that the P2P mobile terminal can publish, index and retrieve resources on the Index Server, and collect the real-time state and cache content resource through Resource Management...
This paper proposes a system aiming to enable family member with mobile phone to share files with other family members with a PC at home no matter whether the mobile phone user is outside the home environment or inside the home environment. We adopt IMS network in our system in the case that mobile phone user is outside the home environment and deploy a Storage Server to forward files when the PC...
Bamboo is one structured P2P overlay, that likes others (e.g. Chord, Kademlia, Pastry), organizes peers into a flat overlay network and offers distributed hash table (DHT) functionality. It is very promising for its efficient routing performance. However, one disadvantage impeding the DHT algorithm popularity is the routing information maintenance overhead; it generates considerable network traffic...
Both SIP and various peer-to-peer protocols have been widely deployed, there is little operational experience with SIP using overlay networks. Also, some researches have proposed to leverage peer-to-peer computing to control multimedia sessions in a decentralized manner (P2PSIP) [1]. However, most proposals in research only focused on the design of P2PSIP protocols using one specific DHT overlay....
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...
A number of routing schemes have been proposed to improve the lookup performance of distributed hash table (DHT). There are three representative routing schemes among existing DHTs: recursive routing, semi-recursive routing and iterative routing. To know which routing scheme is more efficient, this paper takes one of the most important DHTs -- Chord as an example to simulate the three representative...
