IEEE Access, 2015Co-Authors: Akhil GuptaAbstract:In the near future, i.e., beyond 4G, some of the prime objectives or demands that need to be addressed are increased capacity, improved data rate, decreased latency, and better quality of service. To meet these demands, drastic improvements need to be made in cellular Network Architecture. This paper presents the results of a detailed survey on the fifth generation (5G) cellular Network Architecture and some of the key emerging technologies that are helpful in improving the Architecture and meeting the demands of users. In this detailed survey, the prime focus is on the 5G cellular Network Architecture, massive multiple input multiple output technology, and device-to-device communication (D2D). Along with this, some of the emerging technologies that are addressed in this paper include interference management, spectrum sharing with cognitive radio, ultra-dense Networks, multi-radio access technology association, full duplex radios, millimeter wave solutions for 5G cellular Networks, and cloud technologies for 5G radio access Networks and software defined Networks. In this paper, a general probable 5G cellular Network Architecture is proposed, which shows that D2D, small cell access points, Network cloud, and the Internet of Things can be a part of 5G cellular Network Architecture. A detailed survey is included regarding current research projects being conducted in different countries by research groups and institutions that are working on 5G technologies.

A Cybertwin based Network Architecture for 6G
2020 2nd 6G Wireless Summit (6G SUMMIT), 2020Co-Authors: Quan Yu, Haibo Zhou, Wei ZhangAbstract:In this paper, we first introduce a new Network paradigm, called cybertwin based Network Architecture for 6G, which consists a cloud-centric Network Architecture and a radio access Network Architecture. The cybertwin serves as communications assistant, Network behavior logger, and digital asset owner. The proposed cloud-centric Network Architecture can allocate computing, caching, communications resources coordinately, support locator/identifier separation, provide some embed security properties, and support the data market for privacy data. The new radio access Network Architecture, which can fully decouple the control and data base stations and entirely separate uplink and downlink, significantly enhance the spectrum utilization, reduce the Network energy consumption and improve the quality of user experience.

Cybertwin: An Origin of Next Generation Network Architecture
IEEE Wireless Communications, 2019Co-Authors: Quan Yu, Yinjin Fu, Ying Li, Wei ZhangAbstract:With the fast development of IoE and its applications, the ever increasing mobile Internet traffic and services bring unprecedented challenges, including scalability, mobility, availability, and security, which cannot be addressed by the current clean-slate Network Architecture. In this article, a cybertwin based next generation Network Architecture is proposed to accommodate the evolution from end-to-end connection to cloud-toend connection in the future Network. As a digital representation of humans or things in the virtual cyberspace, cybertwin serves in multiple capacities, such as communications assistant, Network behavior logger, and digital asset owner. The new and unique characteristics of the cybertwin make the proposed Network flexible, scalable, reliable, and secure. Further, we advocate a new cloud Network operating system which can work in a distributed way through a real-time multi-agent trading platform to allocate 3C (computing, caching, communication) resources. We also propose cloud operator, a new operator that can provide and manage the resources to the end users and offer location and authentication services for humans and things in cyberspace. Some promising and open research topics are discussed to envision the challenges and opportunities of the cybertwin in the future Network Architecture.

IoT Enabled UAV: Network Architecture and Routing Algorithm
IEEE Internet of Things Journal, 2019Co-Authors: Qixun Zhang, Menglei Jiang, Zhiyong Feng, Wei Li, Wei ZhangAbstract:Unmanned aerial vehicles (UAVs) can be deployed efficiently to provide high quality of service for Internet of Things (IoT). By using cooperative communication and relay technologies, a large swarm of UAVs can enlarge the effective coverage area of IoT services via multiple relay nodes. However, the low latency service requirement and the dynamic topology of UAV Network bring in new challenges for the effective routing optimization among UAVs. In this paper, a layered UAV swarm Network Architecture is proposed and an optimal number of UAVs is analyzed. Furthermore, a low latency routing algorithm (LLRA) is designed based on the partial location information and the connectivity of the Network Architecture. Finally, the performance of the proposed LLRA is verified by numerical results, which can decrease the link average delay and improve the packet delivery ratio in contrast to traditional routing algorithms without layered Architecture.

Network Architecture for home energy management system
International Conference on Consumer Electronics, 2003Co-Authors: Masahiro Inoue, Noriyuki Kushiro, Toshiyasu Higuma, H. KubotaAbstract:This paper describes a Network Architecture for home energy management system (HEMS). To realize HEMS, Networked appliances with control/monitor capabilities and home Network without new wiring are indispensable. However, appliances with no expansive functions and conventional power-line carrier communication deteriorated by its interference have made it difficult to built advanced HEMS. We propose Network Architecture to solve these problems. The Network capability is divided to, minimum interface software embedded in appliance and a separated Network adapter. This Architecture gives appliances Network-ready capabilities without increasing cost. Dispersed-tone power line communication (DTPLC) was also developed for no-new-wire Network. DTPLC modem avoids narrow-band power line noise and co-exists with conventional narrow-band power line communication. Network adapter with DTPLC modem was implemented and the Network Architecture proved effective in the field evaluation of HEMS.

Proceedings of the 6th International ICST Conference on Broadband Communications Networks and Systems, 2009Co-Authors: Yan Wang, Jiazhi Zeng, Ming Liu, Yue Wu, Haigang GongAbstract:In this paper we use Software Engineering methods and Shannon's Communication Model to investigate computer Network Architecture. We get a new type of computer Network Architecture and some significant conclusions. At the first phase of the life cycle of Software Engineering, that is, requirement analysis, we get a series of unexpected conclusions. For example, a variety of computer Network Architectures could be established and evaluated. And the best Architecture could be derived. What is more, protocol stack/ framework could be established and evaluated in order to satisfy special function demands. If the other phases of the life cycle of Software Engineering are executed, the end system and router (switches) in special OS environment could be achieved.

PDCAT - Research on New Types of Network Architecture
Sixth International Conference on Parallel and Distributed Computing Applications and Technologies (PDCAT'05), 2005Co-Authors: Yan Wang, Fasheng Yi, Jiazhi ZengAbstract:Present practical Network Architectures are all constructed with layers. But with the rapid development of Internet, the limitations of layered Network Architecture are more and more outstanding. The layered structure makes it difficult to introduce new technologies, standards and protocols into existing Network Architecture. In addition it is an urgent problem to be resolved that the redundant operation in the different layers causes the performance of the Network to drop. To resolve the limitations of layered Network Architecture, new types of Network Architecture arise. This paper presents three new types of Network Architecture: Object- Oriented Network Architecture, Service Unit based Network Architecture (SUNA) and Role-Based Network Architecture (RBA).

Service unit based Network Architecture
Parallel and Distributed Computing, Applications and Technologies, 2003. PDCAT'2003. Proceedings of the Fourth International Conference on, 2003Co-Authors: Jiazhi Zeng, Yan Fei Wu, Yichao Li, Jie Xu, Neng XuAbstract:There are some limitations of current Network Architectures including functional duplication, error detection in multilayers and the repetition of addresses etc. We propose a novel Network Architecture called service unit based Network Architecture (SUNA). A node in the SUNA is reduced from the current 5- or 7-layers to two layers, i.e. an application layer on the top and a service layer underneath. Such reduction enables all the redundant functions and excessive overheads in existing Network Architecture to be wiped off, and hence improves the Network performance and flexibility. A fringe benefit of the SUNA is to bridge the gap between Network Architectures and programmers and to enable protocol implementation to be carried out in a way that programmers are familiar with.
