The unprecedented surge in mobile data traffic, along with the wide range of services and corresponding different performance requirements, has raised need for a new network architecture. In that sense, 5G been conceived as software defined able to provide service-tailored connectivity. Network slicing is key mechanism serve efficiently diversified service requirements. this paper, we formulate joint RAN functional split optimization centralization degree (CD) throughput. Our results show...
Softwarization of Next Generation-Radio Access Network (NG-RAN) comes along with virtualization Functions (NFs) as purely software-based applications, distributed among a Central Unit (CU) and Distributed Units (DU). This article demonstrates the benefits NG-RAN softwarization that enable Mobile Operators (MNOs) to adopt cutting-edge technologies maximize network efficiency. In this article, we focus on standardization virtualized (vDU), describe features intended boost performance resource...
5G mobile networks are envisioned to substantiate new vertical services with diverse performance requirements. Slicing in the radio access network (RAN) promises an efficient solution for these diversified needs of networks, which foresees separation base station functionality between central unit (CU) and distributed remote heads. In this article, we formulate a mixed integer programming (MIP) framework that maximizes throughput by jointly selecting optimal functional split routing path...
Next-Generation (NG) mobile networks are expected to revolutionize wireless communication systems, facilitating the deployment of critical applications with stringent Quality Service (QoS) requirements. Multi-access Edge Computing (MEC) and Radio Access Network (RAN) slicing considered vital mechanisms upcoming NG systems as they allow creation end-to-end isolated RAN slices increase serving data traffic on edge. The efficient functions promises flexible disaggregated architectures for...
The virtualization of the fifth generation radio access network (RAN), which distributes next Node B functions between a central unit (CU) and distributed (DU), along with emergence slicing as corner-stone mobile communications networks, pose new challenges. One these challenges is management joint allocation appropriate distribution CU DU, known functional split. In this work, discussion on open issues splitting presented, taking into account additional complexity resulting from...
Wireless Sensor Networks (WSN) have lately been gaining momentum thanks to the hardware improvements and standardization software efforts. Moreover, appearance of Internet Things (IoT) its reliance on sensors are helping widely extend usage WSNs. However, such networks present drawbacks, mainly because limited sensor batteries their vulnerability against physical attacks due lack protection security. Additionally, not all inside network same responsibility in terms traffic handling. In this...
The advent of the Fifth Generation (5G) and Beyond (B5G) mobile communications has led to emergence novel vertical services, necessitating reconfiguration network architecture address stringent Quality Service (QoS) demands, while simultaneously supporting reliable Vehicle-to-everything (V2X) communications. In this paper, our primary focus lies in enhancing QoS V2X applications utilizing Open Radio Access Network (O-RAN) architecture. To end, we propose a optimization framework that creates...
Energy Efficiency of a wireless sensor network (WSN) relies on its main characteristics, including hop-number, user's location, allocated power, and relay. Identifying nodes, which have more impact these is, however, subject to substantial computational overhead energy consumption. In this paper, we proposed an active learning approach address the identifying critical nodes in WSN. The can overcome biasing non-critical needs much less effort fine-tuning adapt dynamic nature This method...
