Abstract
The retrieval facilities of most Peer-to-Peer (P2P) systems are limited to queries based on unique identifiers or small sets of keywords. Unfortunately, this approach is very inadequate and inefficient when a huge amount of multimedia resources is shared. To address this major limitation, we propose an original image and video sharing system, in which a user is able to interactively search interesting resources by means of content-based image and video retrieval techniques. In order to limit the network traffic load, maximizing the usefulness of each peer contacted in the query process, we also propose the adoption of an adaptive overlay routing algorithm, exploiting compact representations of the multimedia resources shared by each peer. Experimental results confirm the validity of the proposed approach, that is capable of dynamically adapting the network topology to peer interests, on the basis of query interactions among users.
Highlights
Peer-to-Peer (P2P) networks are distributed systems in which each node runs software with equivalent functionality, in order to operate without requiring central coordination [1]
The P2P paradigm has emerged in the past few years, mainly due to file sharing systems such as Napster [2] and Gnutella [3]
It is well known that consumers are gathering more and more digital multimedia contents
Summary
Peer-to-Peer (P2P) networks are distributed systems in which each node runs software with equivalent functionality, in order to operate without requiring central coordination [1]. The P2P paradigm has emerged in the past few years, mainly due to file sharing systems such as Napster [2] and Gnutella [3]. In the research community there has been an intense interest in designing and studying P2P systems. Due to their decentralization, these systems promise improved robustness and scalability. Consumers capture contents using their digital cameras, digital camcorders, and mobile phones; and store them on different devices. They nowadays tend to store their data in such quantity, as it is becoming increasingly difficult for them to manage, to find and, in the end, to enjoy the videos and images they create
