Multi-Connectivity in 5G and Beyond Non-Terrestrial Networks

2022

The Fifth Generation (5G) communications systems aim to serve such service classes as Ultra-Reliable Low Latency Communications (URLLC), enhanced Mobile Broadband (eMBB), and massive Machine-Type Communications (mMTC). To meet the growing requirements posed to mobile networks, satellites can be used to complement the Terrestrial Networks (TNs). To increase the efficiency of the satellite communications involved, bandwidth-efficient techniques should be used. Multi- Connectivity (MC) is one such technique. In MC, a User Equipment (UE), for example, a smartphone, can be connected to multiple Next Generation Node Bs (gNBs) simultaneously. In this paper, an adaptive MC activation scheme for thr…

Self-configuring multipath intra-mesh infrastructure QoS based routing

2016

International audience; Multi-path routing concept was largely exploited in wireless networks to provide benefits such as fault tolerance, load balancing, performance improvement in terms of latency, etc. In this paper, we propose a multi-path routing based protocol named MP-IMRR (Multi-path Intra-Mesh infrastructure Routing protocol) to improve our previously defined QoS based routing protocol for wireless mesh networks (i.e. IMRR). MP-IMRR is defined in order to achieve better reactivity and faster recovery from eventual route failures than the IMRR protocol by adopting the backup routes concept. Besides, given the complexity increase while considering network management systems, we adopt…

Multi-Connectivity for User Throughput Enhancement in 5G Non-Terrestrial Networks

2022

To meet the increasing throughput and reliability demands, satellites may be used to complement the Fifth Gener-ation (5G) Terrestrial Networks (TNs). To increase the efficiency of the satellite communications involved, research on bandwidth-efficient techniques is needed. Multi-Connectivity (MC), where a user can be connected to multiple Next Generation Node Bs (gNBs) simultaneously, is one of such techniques. In this paper, the focus is on MC in NonTerrestrial Networks (NTNs) to improve users' experienced throughputs. First, a study of relevant specifications and algorithms is conducted. Then, the designed load-aware Secondary Node (SN) addition and traffic steering algorithms are present…

HQMR: Hybrid QoS based Routing Protocol for Wireless Mesh Environment

2015

International audience; Wireless Mesh Networks (WMNs) have been attracting more and more interest from both academic and industrial environments for their seamless broadband connectivity to Internet networks. Besides, providing QoS guarantees for real-time and streaming applications such as Voice over IP (VoIP) and Video on Demand (VoD) is a challenging issue in such environment. Thus, we propose a novel QoS based routing protocol for wireless mesh infrastructure, called Hybrid QoS Mesh Routing (HQMR). Moreover, a clustering algorithm is developed to enhance scalability issues within the mesh infrastructure. HQMR is composed of two routing sub-protocols: a reactive routing protocol for intr…
