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 ...
In off-line packetized streaming, rateless forward error correction (FEC) codes spectacularly improve the reliability of transmission over lossy networks. This success relies on time diversity, which in its turn relies on unrestricted buffering time at the ...
This paper presents a receiver-driven video delivery algorithm that exploits a novel Randomized Network Coding (RNC) scheme for unequal error protection (UEP). The main idea of our approach is to account for the unequal importance of media packets in the n ...
In off-line streaming, packet level erasure resilient forward error correction (FEC) codes rely on the unrestricted buffering time at the receiver. In real-time streaming, the extremely short playback buffering time makes FEC inefficient for protecting a s ...
Network coding has recently emerged as an alternative to traditional routing algorithms in communication systems. In network coding, the network nodes can combine the packets they receive before forwarding them to the neighbouring nodes. Intensive research ...
This paper presents a framework for efficiently streaming scalable video from multiple servers over heterogeneous network paths. We propose to use rateless codes, or Fountain codes, such that each server acts as an independent source, without the need to c ...
Routing packets is a central function of multi-hop wireless networks. Traditionally, there have been two paradigms for routing, either based on the geographical coordinates of the nodes (geographic routing), or based on the connectivity graph (topology-bas ...
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 ...
Using forward error correction (FEC) in off-line streaming, permitting large buffers, yields spectacular results, but real-time streaming puts hard restrictions on the buffer size and therefore does not allow FEC to deal with long link failures on a single ...
Wireless networking technologies allow computing devices to move while keeping them online, but the device mobility poses considerable technical challenges. Network designers, on the one hand, consider mobility to be harmful because it leads to dynamic and ...
