Random Linear Network Coding for 5G Mobile Video Delivery
An exponential increase in mobile video delivery will continue with the
demand for higher resolution, multi-view and large-scale multicast video
services. Novel fifth generation (5G) 3GPP New Radio (NR) standard will bring a
number of new opportunities for optimizing video delivery across both 5G core
and radio access networks. One of the promising approaches for video quality
adaptation, throughput enhancement and erasure protection is the use of
packet-level random linear network coding (RLNC). In this review paper, we
discuss the integration of RLNC into the 5G NR standard, building upon the
ideas and opportunities identified in 4G LTE. We explicitly identify and
discuss in detail novel 5G NR features that provide support for RLNC-based
video delivery in 5G, thus pointing out to the promising avenues for future
research.Comment: Invited paper for Special Issue "Network and Rateless Coding for

Multi-Connectivity Management and Orchestration Architecture Integrated With 5g Multi Radio Access Technology Network
The significant growth in the number of devices and the tremendous boost in
network/user traffic types and volume as well as the efficiency constraints of 4G
innovations have encouraged industry efforts and also financial investments towards
defining, developing, and releasing systems for the fifth generation. The 5G of mobile
broadband wireless networks with multiple Radio Access Technologies (Multi-RATs)
have actually been designed to satisfy the system and service requirements of the
existing as well as the coming applications. The multi-RAT access network is
considered the key enabling technology to satisfy these requirements based on low
latency, high throughput. To utilize all available network resources efficiently, research
activities have been proposed on multi-connectivity to connect, split, steer, switch, and
orchestrate across multiple RATs. Recently, multi-connectivity management and
orchestration architecture standardization has just started; therefore, further study and
research is needed. This project proposed a multi-connectivity management and
orchestration architecture integrated with 5G, Long-Term Evolution (LTE), and
Wireless LANs (WLAN) technologies. The simulations experiments conducted to
measure the Quality of Experience (QoE) by provisioning network resources
efficiently, which are: data rate, latency, bit error rate. The results show that the 5G
requirements have been achieved with latency and throughput around 1ms and 200
Mbps, respectively
Flexible connectivity and QoE/QoS management for 5G networks: the 5G NORMA view
Proceeding of: 2016 IEEE International Conference on Communications Workshops (ICC)The goal envisioned by 5G NORMA is to develop a novel, adaptive and future-proof 5G mobile network architecture. In order to fulfill these requirements, 5G NORMA envisions an extremely flexible architecture to be deployed in a multi-tier distributed data-center. In this paper we focus on the novel mobility management schemes, QoE/QoS, Control and Orchestration mechanisms that are being developed in 5G NORMA. These modules, that follow the software-defined principle, jointly optimize core and access functions. The final result is a modular architecture that adapts to the requirements of very heterogeneous services, while allowing multiple tenants to share network resources among them, providing hence the flexible connectivity needed by future 5G Networks.This work has been performed in the framework of the H2020-ICT-2014-2 project 5G NORMA
Network slicing with flexible mobility and QoS/QoE support for 5G networks
Proceeding of: 2017 IEEE International Conference on Communications. Workshops (ICC Workshops)Network slicing is an emerging area of research, featuring a logical arrangement of resources to operate as individual networks, thus allowing for massively customizable service and tenant requirements. The focus of this paper is to present the design of a flexible 5G architecture for network slicing, building on SDN and NFV technologies as enablers. More specifically, we place the emphasis on techniques that provide efficient utilization of substrate resources for network slicing, ultimately optimizing network performance. The key areas of consideration in our architecture revolve around flexible service-tailored mobility, service-aware QoS/QoE control as well as network-wide orchestrationThis research work has been performed in the framework of H2020-ICT-2014-2 project 5G NORMA
