TCP BBR is one of the most powerful congestion control algorithms. In this article, we provide a comprehensive review of BBR analysis, expanding on existing knowledge across various fronts. Utilising ns3 simulations, we evaluate BBR's performance under diverse conditions, generating graphical representations. Our findings reveal flaws in the probe's RTT phase duration estimation and unequal bandwidth sharing between BBR and CUBIC protocols. Specifically, we demonstrated that the probe's RTT phase duration estimation algorithm is flawed and that BBR and CUBIC generally do not share bandwidth equally. Towards the end of the article, we propose a new improved version of TCP BBR which minimises these problems of inequity in bandwidth sharing and corrects the inaccuracies of the two key parameters RTprop and cwnd. Consequently, the BBR' protocol maintains very good fairness with the Cubic protocol, with an index that is almost equal to 0.98, and an equity index over 0.95.

Aim/Purpose: 5G and IoT are two path-breaking technologies, and they are like wall and climbers, where IoT as a climber is growing tremendously, taking the support of 5G as a wall. The main challenge that emerges here is to secure the ecosystem created by the collaboration of 5G and IoT, which consists of a network, users, endpoints, devices, and data. Other than underlying and hereditary security issues, they bring many Zero-day vulnerabilities, which always pose a risk. This paper proposes a security solution using network slicing, where each slice serves customers with different problems. Background: 5G and IoT are a combination of technology that will enhance the user experience and add many security issues to existing ones like DDoS, DoS. This paper aims to solve some of these problems by using network slicing and implementing an Intrusion Detection System to identify and isolate the compromised resources. Methodology: This paper proposes a 5G-IoT architecture using network slicing. Research here is an advancement to our previous implementation, a Python-based software divided into five different modules. This paper’s amplification includes induction of security using pattern matching intrusion detection methods and conducting tests in five different scenarios, with 1000 up to 5000 devices in different security modes. This enhancement in security helps differentiate and isolate attacks on IoT endpoints, base stations, and slices. Contribution: Network slicing is a known security technique; we have used it as a platform and developed a solution to host IoT devices with peculiar requirements and enhance their security by identifying intruders. This paper gives a different solution for implementing security while using slicing technology. Findings: The study entails and simulates how the IoT ecosystem can be variedly deployed on 5G networks using network slicing for different types of IoT devices and users. Simulation done in this research proves that the suggested architecture can be successfully implemented on IoT users with peculiar requirements in a network slicing environment. Recommendations for Practitioners: Practitioners can implement this solution in any live or production IoT environment to enhance security. This solution helps them get a cost-effective method for deploying IoT devices on a 5G network, which would otherwise have been an expensive technology to implement. Recommendation for Researchers: Researchers can enhance the simulations by amplifying the different types of IoT devices on varied hardware. They can even perform the simulation on a real network to unearth the actual impact. Impact on Society: This research provides an affordable and modest solution for securing the IoT ecosystem on a 5G network using network slicing technology, which will eventually benefit society as an end-user. This research can be of great assistance to all those working towards implementing security in IoT ecosystems. Future Research: All the configuration and slicing resources allocation done in this research was performed manually; it can be automated to improve accuracy and results. Our future direction will include machine learning techniques to make this application and intrusion detection more intelligent and advanced. This simulation can be combined and performed with smart network devices to obtain more varied results. A proof-of-concept system can be implemented on a real 5G network to amplify the concept further.

GSTR-5GQoE - Quality of experience (QoE) requirements for real-time multimedia services over 5G networks

Celona reacts to the growing maturity of its channel by moving from a single-tier organization to a more diverse three tiered one, while complementing the channel announcement with new Aerloc security improvements for industrial IoT.

Updated at 4 p.m. ET Months after approving some limited involvement by the Chinese technology giant Huawei in constructing the U.K.'s next-generation wireless data network, British regulators reversed course Tuesday. Beginning in January, U.K. regulators will implement a ban on telecom operators buying Huawei equipment. Existing Huawei 5G equipment will need to be removed from the U.K.'s 5G network by 2027. The decision comes after relations between the U.K. and China declined sharply over China's actions in Hong Kong, and in the face of a potential rebellion by parliamentarians from the U.K.'s ruling Conservative party who are concerned about the security implications of Chinese involvement in the 5G rollout. But it also follows sustained U.S. pressure on the U.K. and other European countries to exclude Huawei from 5G development. The U.S. says Huawei's equipment can be used for espionage by Beijing, and it has threatened to withhold intelligence from its allies that continued to use

Reliance Jio’s True 5G network can improve the smartphone’s battery life by up to 40 percent, a company official highlighted during the company’s earnings call for the second quarter (Q2) of FY25. The telecommunications provider leverages a standalone (SA) architecture along with other technical features for its 5G services in India and assigns the spectrum bandwidth as per the application.

Reliance Jio's ambitious rollout of its True 5G network across India is not just about faster internet speeds or improved connectivity. One of the less talked about, yet significant benefits is the potential enhancement of smartphone battery life. During the company's

PRAGUE (AP) — The Czech Republic and the United States have signed a joint declaration Wednesday for cooperating on security of 5G technology. The Czech government office said the document was signed remotely by Czech Prime Minister Andrej Babis and U.S. Secretary of State Mike Pompeo. The signing comes amid a global battle between the […]

Prime Minister Boris Johnson will reportedly announce the news before year's end, in a move that could disrupt relationships between the UK and US government.

Chinese telecoms company Huawei has defended its role in the development of 5G in the UK and said disrupting its involvement would "do Britain a disservice".

The company has now expanded its super fast connections to new locations across the UK including Bath, Birkenhead, Motherwell and Rotherham.

5G will help in easing out on the network congestion thereby improving user experience while streaming videos across platforms. It will also provide a smart data pipe for content; monetize broadcast spectrum and provide live streaming on-the-go sans data caps.
