网络中的非自适应分布式压缩

Non-Adaptive Distributed Compression in Networks

Mahdy Nabaee, Fabrice Labeau

摘要:

在本文中,我们讨论了非自适应分布式压缩节点间相关的实值消息。要做到这一点,我们讨论了传统的数据包通过路由转发的性能,在总的网络负载与所产生的服务质量(失真水平)。作为一个更好的替代数据包转发,我们简要地描述了我们以前提出的一步量化网络编码(QNC),并使激励参数的优势时,适当的边际速率分布式信源编码是不可用的编码器源节点。我们还得到分析保证我们的一步QNC方案所产生的失真。最后,我们得出结论,通过提供一步QNC和传统的数据包转发的总网络负载之间的数学比较,一步QNC的情况下显着减少。

英文摘要:

In this paper, we discuss non-adaptive distributed compression of inter-node correlated real-valued messages. To do so, we discuss the performance of conventional packet forwarding via routing, in terms of the total network load versus the resulting quality of service (distortion level). As a better alternative for packet forwarding, we briefly describe our previously proposed one-step Quantized Network Coding (QNC), and make motivating arguments on its advantage when the appropriate marginal rates for distributed source coding are not available at the encoder source nodes. We also derive analytic guarantees on the resulting distortion of our one-step QNC scenario. Finally, we conclude the paper by providing a mathematical comparison between the total network loads of one-step QNC and conventional packet forwarding, showing a significant reduction in the case of one-step QNC.
