The Road Ahead for Networking: A Survey on ICN-IP Coexistence Solutions

In recent years, the current Internet has experienced an unexpected paradigm shift in the usage model, which has pushed researchers towards the design of the Information-Centric Networking (ICN) paradigm as a possible replacement of the existing architecture. Even though both Academia and Industry have investigated the feasibility and effectiveness of ICN, achieving the complete replacement of the Internet Protocol (IP) is a challenging task. Some research groups have already addressed the coexistence by designing their own architectures, but none of those is the final solution to move towards the future Internet considering the unaltered state of the networking. To design such architecture, the research community needs now a comprehensive overview of the existing solutions that have so far addressed the coexistence. The purpose of this paper is to reach this goal by providing the first comprehensive survey and classification of the coexistence architectures according to their features (i.e., deployment approach, deployment scenarios, addressed coexistence requirements and architecture or technology used) and evaluation parameters (i.e., challenges emerging during the deployment and the runtime behaviour of an architecture). We believe that this paper will finally fill the gap required for moving towards the design of the final coexistence architecture.Comment: 23 pages, 16 figures, 3 table

The Evolution of 5G Communications within the Scope of the Fourth Industrial Revolution

A Quarta Revolução Industrial é uma consequência da última transformação digital e consiste na substituição de seres humanos por robôs. Está associada à utilização massiva de robôs, inteligência artificial, grandes dados, Internet das Coisas (IoT), computação quântica ou impressão 3D. A transformação digital e a transformação ambiental estão amplamente associadas, uma vez que a primeira permite uma utilização mais eficiente dos recursos, o que tende a reduzir a pegada de carbono, e permite a geração de energias renováveis. A Quinta Geração de Comunicações Celulares (5G) é disruptiva, uma vez que consiste numa mudança de paradigma relacionado com as gerações anteriores. As Comunicações 5G dão uma forte contribuição para a implementação da Quarta Revolução Industrial numa vasta gama de áreas, tais como em veículos autónomos, cidades inteligentes, indústrias e agricultura inteligentes, cirurgias remotas, etc. Enquanto as comunicações 5G visam implementar alguns dos requisitos da Quarta Revolução Industrial, a Sexta Geração de Comunicações Celulares (6G), prevista para 2030, visa complementar essa implementação de uma forma mais profunda.The Fourth Industrial Revolution is a consequence of the latest digital transformation and consists of the replacement of humans by robots. It is associated to the massive use of robots, artificial intelligence, big data, Internet of Things (IoT), quantum computing or 3D printing. Digital transformation and environmental transformation are widely associated as the former allows a more efficient use of the resources, which tends to reduce the carbon footprint, and allows the generation of renewable energies. The Fifth Generation of Cellular Communications (5G) is disruptive, as it consists of a change of paradigm relating to the previous generations. 5G Communications give a strong contribution to the implementation of the Fourth Industrial Revolution in a wide range of areas, such as in autonomous vehicles, smart cities, smart industries and agriculture, remote surgeries, etc. While 5G communications aim to implement some of the requirements of the Fourth Industrial Revolution, the Sixth Generation of Cellular Communications (6G), expected by 2030, aims to complement such implementation in a deeper manner.La Cuarta Revolución Industrial es una consecuencia de la última transformación digital y consiste en la sustitución de los humanos por robots.

A Method for Securing Symmetric Keys for Internet of Things Enabled Distributed Data Systems

This study introduces an innovative method for securing symmetric keys in Internet of Things (IoT)-enabled distributed data systems, focusing on enhancing data security while optimizing encryption and decryption times. Through a comprehensive analysis of various encryption algorithms—TEA, XTEA, BLOCK TEA (XXTEA), and the proposed NTSA algorithm—across different key sizes and file sizes, we aim to demonstrate the significant improvements our method offers over existing techniques. Our research meticulously evaluated the performance of these algorithms, employing random variations to encryption and decryption times to simulate real-world variability and assess the algorithms' efficiency and security robustness. The findings reveal that the NTSA algorithm, in particular, showcases superior performance, offering an approximate improvement of 10% to 15% in encryption and decryption times over traditional methods such as TEA and XTEA, and an even more considerable enhancement compared to BLOCK TEA (XXTEA). The key contribution of this study lies in its provision of a secure, efficient framework for symmetric key encryption in IoT-enabled distributed environments. By optimizing key size and algorithm selection, our method not only secures data against potential cyber threats but also ensures high-speed data processing—a critical requirement in the IoT domain where the volume of data transactions and the need for real-time processing are ever-increasing. The proposed method significantly advances the field of data security in distributed systems, especially within the context of the burgeoning IoT landscape. It underscores the importance of algorithmic efficiency and strategic key management in bolstering the security and performance of modern digital ecosystems

Coordinated Dynamic Spectrum Management of LTE-U and Wi-Fi Networks

This paper investigates the co-existence of Wi-Fi and LTE in emerging unlicensed frequency bands which are intended to accommodate multiple radio access technologies. Wi-Fi and LTE are the two most prominent access technologies being deployed today, motivating further study of the inter-system interference arising in such shared spectrum scenarios as well as possible techniques for enabling improved co-existence. An analytical model for evaluating the baseline performance of co-existing Wi-Fi and LTE is developed and used to obtain baseline performance measures. The results show that both Wi-Fi and LTE networks cause significant interference to each other and that the degradation is dependent on a number of factors such as power levels and physical topology. The model-based results are partially validated via experimental evaluations using USRP based SDR platforms on the ORBIT testbed. Further, inter-network coordination with logically centralized radio resource management across Wi-Fi and LTE systems is proposed as a possible solution for improved co-existence. Numerical results are presented showing significant gains in both Wi-Fi and LTE performance with the proposed inter-network coordination approach.Comment: Accepted paper at IEEE DySPAN 201
