Online fountain code with an improved caching mechanism
IET CommunicationsThe original online fountain codes discard a large number of symbols that do not meet the requirements at the decoder. To improve channel utilization, this article proposes a new online fountain code.

Linearly-Coupled Fountain Codes
, 2014 Network-coded multiple access (NCMA) is a communication scheme for wireless multiple-access networks where physical-layer network coding (PNC) is employed. In NCMA, a user encodes and spreads its message into multiple packets. Time is slotted and multiple users transmit packets (one packet each) simultaneously in each timeslot.

Fountain Coded Wireless Transmission Model
Indian Journal of Science and Technology, 2016 Background/Objectives: Rateless codes have recently attracted much engrossment in community communication research as the Luby Transform codes and Raptor codes are most renowned. The Fountain codes do not have the requirement of the receiver to inform the transmitter of the identity of the packets that are corrupted resulting in expelling the need of ...

Energy-Efficient Channel Coding Strategy for Underwater Acoustic Networks
Sensors, 2017 Underwater acoustic networks (UAN) allow for efficiently exploiting and monitoring the sub-aquatic environment. These networks are characterized by long propagation delays, error-prone channels and half-duplex communication. In this paper, we address the

Analysis and Design of Rateless Two-way Relay Networks Based on a Multiply-and-Forward Scheme
Applied Sciences, 2020 In this paper, we propose a rateless, three-stage, two-way multiply-and-forward (MF) relaying system over the Rayleigh flat fading channel, where two source nodes communicate with each other through a relay node and all nodes work on half-duplex and time-

Raptor codes for infrastructure-to-vehicular broadcast services [PDF]
, 2011 One of the important applications to be available in vehicular ad-hoc networks are value-added or infotainment services. However, vehicular communication suffers from high packet loss due to challenging channel characteristics such as huge Doppler spread

Multilevel Network Steganography in Fountain Codes [PDF]
European Interdisciplinary Cybersecurity Conference, 2021 We present a method to establish a network storage covert channel in a fountain code, which is used to provide reliable communication over lossy network with low overhead and without acknowledgment. As also parts of the secret message get lost when a carrier packet is lost, reliable transmission of the secret message is provided by using a second ...
