It investigates a QoS provisioning with vertical multi-homing and multistreaming features for 5G heterogeneous networks. The presented enhanced framework for 5G systems leads to better performance opportunities for multimedia services with very high level of QoS provisioning in different radio access network (RAN) conditions. The system framework is user-centric oriented, with ability to simultaneously handle multiple RAN connections, choosing the most appropriate RAN for each used service. This paper evaluates the key QoS parameters for multimedia traffic in heterogeneous mobile and wireless scenarios were multiple RANs coexist in the simulation set up. The simulation scenarios includes 3G, 4G, and 5G radio access networks and use Genetic Algorithm and Linear Programming algorithm to solve the optimization problem. The analysis shows significantly high QoS performance for the achievable aggregated throughput and multimedia access probability ratio in heterogeneous wireless and mobile environment, especially in case of large number of available heterogeneous nodes.

In addition, the data generating process is heterogeneous, and the data is enormous in bulk, requiring complicated management. Quantum IoT, or Quantum Computing and IoT, is a notion of higher security design that utilizes quantum-mechanical principles on IoT security management. On the one hand, IoT is beneficial to us, but it also poses several major security risks, such as data leaks, side-channel attacks, malware, and data authentication. Classical cryptographic techniques, such as the Rivest-Shamir-Adleman (RSA) algorithm, perform admirably on traditional machines. However, quantum computing, which has enormous processing capacity and is more than capable of readily breaking current cryptographic algorithms, is steadily gaining traction. As a result, even before quantum computers are commerc...

The proposed 5G framework is leading to high QoS provisioning for any given multimedia service, higher bandwidth utilization, traffic load sharing, mobile cloud plus fog computing features, and multi-radio interface capabilities. The framework is user-centric, targeted at always-on connectivity with using radio network aggregation for available mobile broadband connections, and empowered with mobile cloud and fog computing advantages. Moreover, our proposed framework is using Lyapunov drift-plus-penalty theorem that provides a methodology for designing algorithm to maximize the average throughput and stabilize the queuing. Also, we are showing the upper bound of the consumed power and the lower bound of the battery lifetime for the proposed 5G terminal. The advanced performance of our 5G QoS plus MCC framew...

In today's digital age, individuals, groups and some states, (ab)use the easy access to modern technologies to further their economic and political objectives. In these endeavors, among others, these actors utilize jamming attacks (i.e. electronic warfare tactics exclusively used by the military in the past), in order to produce the well-known effect of DoS (Denial of Service). Up to now there is no communication technology that is immune to the jamming attacks, so there is no expectation that the new 5G concept, that is still under development will be fully resistant to well-known traditional jamming and other types of attacks. The proposed Security and Quality of Service (QoS) framework provides high levels of security features and safety, through high-performance mobile broadband networks, using Mobile Cloud computing. It guarantees QoS provisioning for different broadband services, with present jamming, as well as, other types of distributed DoS (DDoS) attacks. Moreover, the trend of integrating various criminal activities in the cyberspace is also presented. The performance of the proposed security and QoS framework is evaluated through simulations and analysis with multimedia traffic, in a heterogeneous mobile broadband Cloud environment with the coexistence of multiple radio technologies.

The framework is using present and future networks, and the proposed architecture presents an emergency and mission critical data system model, based on the fundamental principles of 5G network architectures. Thus, the end-IoT devices communicate with IoT applications, hosted in cloud servers or edge computing servers. The novel simulation results and analysis present superior system performance with high level of end-to-end reliability depending on the link delays, and at the same time low average end to end outage, based on the link outage. The framework also provides an intelligent solution for high reliability and low end-to-end delay for emergency and mission critical data services and communications, emerging as essential for the security of the society and citizens, by simultaneously using multiple radio access technologies.

The proposed 5G node framework is leading to high performance utility networks with QoS provisioning for any given service, high average throughput and multi-RAT capabilities (part of 5G trends), at the same time achieving stochastic queuing network stability. Proposed framework is using Lyapunov drift-plus-penalty theorem that provides a methodology for designing algorithm to maximize the average throughput and stabilize the queuing. The proposed algorithm implemented within the mobile nodes and proxy node on the mobile network side, is able to handle simultaneously multiple multimedia flows via multiple wireless and mobile interfaces. The performance of the proposed framework for 5G nodes is evaluated with simulation and analytical results. The results show that the given framework achieves maximal aggregated throughput subject to average power constraints on the node interfaces, and at the same time it minimizes average queue backlogs subject to minimal network delay.
