摘要

我们考虑了网络编码传输在擦除广播信道上的吞吐量-延迟权衡。为了最小化解码延迟,我们将即时可解码的网络编码问题表述为一个整数线性规划,并提出了启发式解决该问题的算法。我们特别研究了有内存的信道,并提出了利用信道擦除依赖性来提高吞吐量和降低延迟的算法。

Adaptive network coding for broadcast channels
We consider the throughput-delay tradeoff in network coded transmission over erasure broadcast channels. Interested in minimizing decoding delay, we formulate the problem of instantly decodable network coding as an integer linear program and propose algorithms to solve it heuristically. In particular, we investigate channels with memory and propose algorithms that can exploit channel erasure dependence to increase throughput and decrease delay.
