Optimized Network Coding with Real-Time Loss Prediction for Hybrid 5G Networks

Opportunistic Network Coding for Real-Time Transmission over Wireless Networks

Network coding has shown a good potential for improving network throughput and, recently, has been used in multimedia transmission over wireless networks. In addition to guaranteed throughput, real-time multimedia transmission requires bounded delay, delay variation, and packet loss. This paper presents RTOC, a new XOR-based opportunistic network coding architecture for real-time data transmiss...

Optimized Noisy Network Coding for Gaussian Relay Networks

In this paper, we provide an improved lower bound on the rate achieved by noisy network coding in arbitrary Gaussian relay networks, whose gap to the cutset upper bound depends on the network not only through the total number of nodes but also through the degrees of freedom of the min cut of the network. We illustrate that for many networks this refined lower bound can lead to a better approxim...

Hybrid Image Coding for Real-Time Computer Screen Video Transmission

In this paper, we present a novel hybrid image coding scheme for real-time applications of computer screen video transmission. Based on the Mixed Raster Content (MRC) multilayer imaging model, the background picture is compressed with lossy JPEG, and the foreground layer consisting of text and graphics is compressed with a block-based lossless coding algorithm, which integrates shape-based codi...

Policy Model for Sharing Network Slices in 5G Core Network

As mobile data traffic increases, and the number of services provided by the mobile network increases, service load flows as well, which requires changing in the principles, models, and strategies for media transmission streams serving to guarantee the given nature of giving a wide scope of services in Flexible and cost-effective. Right now, the fundamental question remains what number of netwo...
