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.

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 ...

Noncommutative Wormhole Solutions in Einstein Gauss‐Bonnet Gravity

Advances in High Energy Physics, Volume 2016, Issue 1, 2016., 2016
We explore static spherically symmetric wormhole solutions in the framework of n‐dimensional Einstein Gauss‐Bonnet gravity. Our objective is to find out wormhole solutions that satisfy energy conditions. For this purpose, we consider two frameworks such as Gaussian distributed and Lorentzian distributed noncommutative geometry.

Network Coding Channel Virtualization Schemes for Satellite Multicast Communications

, 2017
In this paper, we propose two novel schemes to solve the problem of finding a quasi-optimal number of coded packets to multicast to a set of independent wireless receivers suffering different channel conditions.

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 ...
