Mathematical Problems in Engineering, Volume 2015, Issue 1, 2015., 2015 We study how to utilize network coding to improve the throughput of secondary users (SUs) in cognitive radio networks (CRNs) when the channel quality is unavailable at SUs. We use a two‐dimensional multiarmed bandit (MAB) approach to solve the problem of SUs with network coding under unknown channel quality in CRNs.

Improved Data Transmission Scheme of Network Coding Based on Access Point Optimization in VANET
Journal of Electrical and Computer Engineering, Volume 2014, Issue 1, 2014., 2014 VANET is a hot spot of intelligent transportation researches. For vehicle users, the file sharing and content distribution through roadside access points (AP) as well as the vehicular ad hoc networks (VANET) have been an important complement to that cellular network. So the AP deployment is one of the key issues to improve the communication performance

Joint Redundant and Random Network Coding for Robust Video Transmission over Lossy Networks
Mobile Information Systems, Volume 8, Issue 3, Page 213-230, 2012., 2012 In this paper a novel unequal packet loss protection scheme R2NC based on low‐triangular global coding matrix with ladder‐shaped partition is presented, which combines redundant and random network coding for robust H.264/SVC video transmission. Firstly, the error‐correcting capabilities of redundant network coding make our scheme resilient to loss ...

From Instantly Decodable to Random Linear Network Coding [PDF]
, 2013 Our primary goal in this paper is to traverse the performance gap between two linear network coding schemes: random linear network coding (RLNC) and instantly decodable network coding (IDNC) in terms of throughput and decoding delay.
