content discovery is one of the fundamental issues that determines the architecture and performance of content distribution networks based on peer-to-peer (p2p) networks. to administrate the costs and discoveries, peers of a p2p network communicate with each other by one or more overlay layers. the condition of node’s relations in overlay networks, have a great impact in efficiency of networks....

In this paper, we propose an innovative system that aims to adapt to the user needs and preferences the media content transmissions within IP and P2P environments. To personalize the manner the content is displayed to the final user, this proposed network allows the transmission of multiple views and different layers for each media content piece. In addition, we suggest an approach on how to de...

Trust between communicating peers is increasingly catching the attention of the research community. Several methods have been proposed to assist the task of establishing trust between communicating peers; all of which make use of reputation mechanisms. We find that in present literature, reputation is incorrectly defined, as some chief aspects of reputation are not considered while defining it....

In the last years, distributed coordinator-free systems, e.g., peerto-peer systems (P2P systems), have attracted much interest among researchers and practitioners. In these systems it is difficult to motivate participants to cooperate. To this end, researchers have proposed various incentive mechanisms. In this paper we are interested in the following question: Do human beings indeed use the st...

Peer-to-peer based gaming is a new paradigm for distributed multiplayer online gaming that has attracted attention in the last years. It is known that P2P based topologies offer good scaling properties and mitigate unfairness otherwise observed for peers being far away and thus having large network lags. However, removing inconsistencies for high paced action games like FPS or tank battle games...

Peer-to-peer is a technology concept applied at different levels of the systems architecture. Its main characteristics are direct interaction and data exchange between peer systems. It is the basis for decentralised distributed computing. The concept is widely deployed in different contexts and no formal definition exists. This paper gives an overview of the different areas peer-to-peer technol...
