Today, the Network Slicing technology is massively addressed by the research community. However, Network Slice (NS) modelling details from Standards Developing Organizations (SDOs) are not yet well considered for End-to-End (E2E) NS implementations. In addition, each SDO develops standards targeting only a specific part of the NS architecture. Therefore, based on a profound analysis of the major e...Show More
Network Slicing is becoming a mature technology in recent years due to the continuous efforts conducted by the standards organizations, academic units and operators.

This paper provides a novel ...Show More
The Random Linear Network Coding (RLNC) has been investigated as a promising solution for improve transmission reliability; however, it is highly susceptible to errors. In wireless sensor networks (WSN), The problem resemblance to a column vector on the generator matrix of Low-Density Parity-Check (LDPC) matrix is caused by the important similarity between received symbols from the cluster head (C...Show More
In narrowband, a Radio spectrum is very limited. In order to be able to communicate more effectively, every user of radio spectrum needs a channel. These channels are often differentiated by their frequency, a radio frequency (RF) channel has frequency bandwidth or channel spacing.
