A peer-to-peer overlay network is a logical network, built on top of a physical network. In contrast to classical client-server distributed architectures, peer-to-peer overlay networks allow location of resources without centralized control. Existing overl ...
This paper addresses the problem of efficiently delivering a layered media stream from multiple senders to a single receiver, over channels that present correlated packet loss patterns. Using a digital fountain approach, the performance of a distributed st ...
Media streaming has found applications in many domains such as education, entertainment, communication and video surveillance. Many of these applications require non-trivial manipulations of media streams, beyond the usual capture/playback operations suppo ...
We consider the problem of rate-distortion (RD) optimized media streaming in unstructured peer-to-peer (P2P) overlay networks. We formulate the aforementioned problem as a distributed rate allocation problem. To solve the problem for all the participating ...
Gossip-based protocols are now acknowledged as a sound basis to implement collaborative high-bandwidth content dissemination: content location is disseminated through gossip, the actual contents being subsequently pulled. In this paper, we present HEAP, HE ...
In this paper we analyze the functional and non-functional requirements of peer-to-peer (P2P) systems that go beyond the needs of the well explored file-sharing P2P systems. Four basic subcategories are suggested to classify the non-functional requirements ...
With the latest developments in video coding technology and fast deployment of end-user broadband internet connections, real-time media applications become increasingly interesting for both private users and businesses. However, the internet remains a best ...
We address the problem of distributed path selection and rate allocation for media streaming in overlay networks. Under the assumption that each node has only a local view of the network, we propose a distributed algorithm for joint path selection, and rat ...
In this paper, we consider the problem of streaming video information on lossy packet networks with path and source diversity, such as wireless mesh networks or more generally overlay architectures. We propose to distribute the video information between se ...
This paper addresses the problem of streaming packetized media over a lossy packet network, with sender-driven (re)transmissions and receiver acknowledgments. It extends the markovian formulation of the rate- distortion optimized (RaDiO) streaming framewor ...
