In peer-to-peer based live streaming systems, a great number of participants have to cooperate to efficiently and reliably distribute a continuous flow of data. Each receiving peer in return provides its resources to the system. Since these systems operate in a completely distributed manner, it is of particular importance, to prevent malicious members from harvesting important topology informat...

Nowadays, the security of P2P networks is alarming ascribing to worms which propagate by exploiting common vulnerabilities in P2P software. Taking account of the topology of P2P networks and the behavior of worms, this paper models the propagation of active worms in unstructured P2P networks. Simulations indicate that propagation of worms in P2P networks is much faster than that in un-P2P netwo...

In this paper we examine the database management of spatiotemporal resource information in mobile peer-to-peer networks, where moving objects communicate with each other via short-range wireless transmission. Several inherent characteristics of this environment, including the dynamic and unpredictable network topology, the limited peer-to-peer communication throughput, and the need for incentiv...

Peer-to-peer (P2P) technologies have been widely used for content sharing, popularly called “file-swapping” networks. This chapter gives a broad overview of content sharing P2P technologies. It starts with the fundamental concept of P2P computing followed by the analysis of network topologies used in peer-to-peer systems. Next, three milestone peer-to-peer technologies: Napster, Gnutella, and F...

At present, most peer-to-peer file sharing systems provide file-mark-based searching function. In the paper, we offer a file recommendation system based on pure peer-to-peer system, use the TOPK method to find similar interest peers in a way to realize the interest-based self-adaptive adjustment of network topology; and exploits the recommendation information between users with similar interest...

As Peer-to-Peer (P2P) quickly gains popularity for its nearly unlimited scalability, the amount of copyright infringing incidents surges even more rapidly. While record industry pleads for prohibiting P2P by lawmakers, academicians and practitioners turn to look for more constructive ways: using P2P as a profitable and legitimate distribution channel. By offering rebate to those who share conte...
