Passive network tomography for erroneous networks: A network coding approach
, 2010 Passive network tomography uses end-to-end observations of network communication to characterize the network, for instance to estimate the network topology and to localize random or adversarial glitches.

A Novel Cooperation‐Based Network Coding Scheme for Walking Scenarios in WBANs
Wireless Communications and Mobile Computing, Volume 2017, Issue 1, 2017., 2017 In Wireless Body Area Networks (WBANs), the tradeoff between network throughput and energy efficiency remains a key challenge. Most current transmission schemes try to cope with the challenge from the perspective of general Wireless Sensor Networks (WSNs), which may not take the peculiarities of WBAN channels into account.

Network Coded Multicast over Multibeam Satellite Systems
Mathematical Problems in Engineering, Volume 2015, Issue 1, 2015., 2015 We propose a multicast scheme for multibeam satellite systems exploiting both the multiuser and spatial diversity inherent in this type of systems while taking into account realistic physical distributions of User Terminals (UTs) over the coverage. Our proposed scheme makes use of the well‐known Adaptive Coding and Modulation (ACM) feature in Digital ...

PACE: Redundancy Engineering in RLNC for Low-Latency Communication
IEEE Access, 2017 Random linear network coding (RLNC) is attractive for data transfer as well as data storage and retrieval in complex and unreliable settings. The existing systematic RLNC approach first sends all source symbols in a generation without encoding followed ...

Review of Rateless‐Network‐Coding‐Based Packet Protection in Wireless Sensor Networks
Mobile Information Systems, Volume 2015, Issue 1, 2015., 2015 In recent times, there have been many developments in wireless sensor network (WSN) technologies using coding theory. Fast and efficient protection schemes for data transfer over the WSN are some of the issues in coding theory. This paper reviews the issues related to the application of the joint rateless‐network coding (RNC) within the WSN in the ...

Localized Dimension Growth in Random Network Coding: A Convolutional Approach [PDF]
, 2011 We propose an efficient Adaptive Random Convolutional Network Coding (ARCNC) algorithm to address the issue of field size in random network coding. ARCNC operates as a convolutional code, with the coefficients of local encoding kernels chosen randomly ...

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
