As a means of resources sharing, peer-to-peer (P2P) networks are currently receiving much attention. However, the open and anonymous nature of P2P networks also paves the way for malicious users to abuse the systems such as disseminating of inauthentic files or even viruses. To counter such menacing vulnerabilities in P2P networks, this paper presents a reputation-based approach that combines personal...
Peer-to-peer networks have become extremely popular over the last decades for one major reason. They make the exchange of files between users easy and fast. Peer-to-peer systems have been proved to be the basis for the creation of worldwide networks where users exchange read-only files freely and efficiently. However, users have started using applications that need more than what the exchange of immutable...
NAT (network address translation) are widely used to isolate the private networks from internet. Unfortunately, NATs block the data transmitted directly between two nodes under different private networks in many peer-to-peer applications. A protocol, STUN (simple traversal of UDP over NATs), has been proposed by IETF to solve the problem, but it costs great network bandwidth and transmission delays...
Despite the popularity of streaming applications over Internet, little is known about its practical properties which could be potentially exploited to guide the system design of next generation peer-to-peer (P2P) networks. In this paper, we hence investigate the problem of understanding and supporting the two types of dominant streaming services - live broadcasting and on-demand streaming - with high...
This paper presents a novel peer selection model named ant peer selection (AntPS) to prevent selecting malicious or selfish peers as service providers in peer-to-peer (P2P) systems. We created two pheromone tables named resource similarity pheromone table and trust similarity pheromone table for every peer in the system. When a peer produces some request messages, a new ant called forward ant (fant)...
