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 ...

Augmented LT codes over binary extension fields with increased ratio of full‐degree columns

Electronics Letters, Volume 60, Issue 5, March 2024.
An augmented scheme of LT codes is proposed to improve the decoding success rate. The method involves substituting the 1 in full‐degree columns of the generator matrix of conventional LT codes with binary extension field elements and simultaneously increasing the ratio of full‐degree columns in the ideal soliton distribution, which allows for higher ...

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 ...

A Two‐Dimensional Multiarmed Bandit Approach to Secondary Users with Network Coding in Cognitive Radio Networks

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.

Fulcrum: Flexible Network Coding for Heterogeneous Devices

IEEE Access, 2018
We introduce Fulcrum, a network coding framework that achieves three seemingly conflicting objectives: 1) to reduce the coding coefficient overhead down to nearly n bits per packet in a generation of n packets; 2) to conduct the network coding using only

Energy Saving and Reliability for Wireless Body Sensor Networks (WBSN)

IEEE Access, 2018
In healthcare and medical applications, the energy consumption of biosensor nodes affects the collection of biomedical data packets, which are sensed and measured from the human body and then transmitted toward the sink node.

Distributed Intrusion Detection of Byzantine Attacks in Wireless Networks with Random Linear Network Coding

International Journal of Distributed Sensor Networks, 2012
Network coding (NC) can be applied to achieve the maximal information flow in a network. In energy-constraint wireless networks such as wireless sensor networks, applying NC can further reduce the number of wireless transmissions and hence prolong the ...
