\"Big Data\" is on the covers ofScience, Nature, theEconomist, andWiredmagazines, on the front pages of theWall Street Journaland theNew York Times.But despite the media hyperbole, as Christine Borgman points out in this examination of data and scholarly research, having the right data is usually better than having more data; little data can be just as valuable as big data. In many cases, there are no data -- because relevant data don't exist, cannot be found, or are not available. Moreover, data sharing is difficult, incentives to do so are minimal, and data practices vary widely across disciplines.Borgman, an often-cited authority on scholarly communication, argues that data have no value or meaning in isolation; they exist within a knowledge infrastructure -- an ecology of people, practices, technologies, institutions, material objects, and relationships. After laying out the premises of her investigation -- six \"provocations\" meant to inspire discussion about the uses of data in scholarship -- Borgman offers case studies of data practices in the sciences, the social sciences, and the humanities, and then considers the implications of her findings for scholarly practice and research policy. To manage and exploit data over the long term, Borgman argues, requires massive investment in knowledge infrastructures; at stake is the future of scholarship.

Resource management in a cloud environment is a hard problem, due to: the scale of modern data centers; the heterogeneity of resource types and their interdependencies; the variability and unpredictability of the load; as well as the range of objectives of the different actors in a cloud ecosystem. Consequently, both academia and industry began significant research efforts in this area. In this paper, we survey the recent literature, covering 250+ publications, and highlighting key results. We outline a conceptual framework for cloud resource management and use it to structure the state-of-the-art review. Based on our analysis, we identify five challenges for future investigation. These relate to: providing predictable performance for cloud-hosted applications; achieving global manageability for cloud systems; engineering scalable resource management systems; understanding economic behavior and cloud pricing; and developing solutions for the mobile cloud paradigm .

The current mobile communications could not satisfy the explosive data requirement of users. This paper reviews the frontier technology of software definition networks (SDN) of 5G and 6G, including system architecture, resource management, mobility management, interference management, challenges, and open issues. First of all, the system architectures of 5G and 6G mobile networks are introduced based on SDN technologies. Then typical SDN-5G/6G application scenarios and key issues are discussed. We also focus on mobility management approaches in mobile networks. Besides, three types of mobility management mechanism in software defined 5G/6G are described and compared. We then summarize the current interference management techniques in wireless cellular networks. Next, we provide a brief survey of interference management method in SDN-5G/6G. Additionally, considering the challenges, we discuss mm-Wave spectrum, un-availability of popular channel model, massive MIMO, low latency and QoE, energy efficiency, scalability, mobility and routing, inter operability, standardization and security for software defined 5G/6G networks.

The rising demand for sustainable information delivery and efficient data transmission in next-generation cloud-enabled non-terrestrial networks necessitates advanced optimization techniques. This paper introduces a novel framework that integrates Power-Domain Non-Orthogonal Multiple Access (PD-NOMA) with Deep Reinforcement Learning (DRL) to optimize satellite constellations and dynamically manage communication links. By leveraging a multi-objective optimization approach, the framework aims to balance key performance indicators, such as link utilization, latency, power efficiency, and network throughput, in satellite communication networks. The proposed methodology is structured into four key stages: (1) Analyzing network data, including user demands in the Mobile Ad Hoc Network, traffic patterns, and satellite positions, to predict future network requirements. (2) Utilizing PD-NOMA for efficient link utilization, enabling multiple users to share the same communication resources, thereby maximizing throughput and minimizing power consumption. (3) Introducing dynamic DRL for adaptive resource allocation and multi-objective optimization of constellation parameters, including satellite positions and communication links. (4) Dynamically adjusting both resource allocation and network configurations in response to real-time network conditions to ensure sustained and optimized performance. Extensive simulations validate the effectiveness of the proposed framework, demonstrating significant improvements in network data rate, energy efficiency, and overall performance. The results indicate that the integration of dynamic link utilization with multi-objective constellation optimization offers an efficient solution for enhancing hierarchical satellite communication systems.

Future intelligent wireless networks demand an adaptive learning approach towards a shared learning model to allow collaboration between data generated by network elements and virtualized functions. Current wireless network learning approaches have focused on traditional machine learning (ML) algorithms, which centralize the training data and perform sequential model learning over a large data set. However, performing training on a large dataset is inefficient; it is time-consuming and not energy and resource-efficient. Transfer Learning (TL) effectively addresses some challenges by training based on a small data set using pre-trained models for similar problems without impacting neural network model performance. TL is a technique that applies the knowledge (features, weights) gained from a previously trained ML model to another but related problem. This work proposes an Adaptive Learning framework ‘ADAPTIVE6G’, a novel approach for a network slicing architecture for resource management and load prediction in data-driven Beyond 5G (B5G), 6G Wireless systems influenced by the knowledge learning from TL techniques. We evaluated ADAPTIVE6G to solve complex network load estimation problems to promote a more fair and uniform distribution of network resources. We demonstrate that the ADAPTIVE6G model can reduce the Mean Squared Error (MSE) by more than 30% and improve the Correlation Coefficient ‘R’ by close to 6% while reducing under-provisioned resources.

In the dynamic environment of the Internet of Things (IoT), edge and cloud computing play critical roles in analysing and storing data from numerous connected devices to produce valuable insights. Efficient resource allocation and workload distribution are vital to ensuring continuous and reliable service in growing IoT ecosystems with increasing data volumes and changing application demands. This study proposes a novel optimisation approach utilising deep learning to tackle these challenges. The integration of Deep Q-Networks (DQN) and Proximal Policy Optimization (PPO) offers a practical approach to addressing the dynamic characteristics of IoT applications. The hybrid algorithm's primary characteristic is its capacity to simultaneously fulfil multiple objectives, including reducing response times, enhancing resource efficiency, and decreasing operational costs. DQN facilitates the formulation of optimal resource allocation strategies in intricate and unpredictable environments. PPO enhances policies in continuous action spaces to guarantee reliable performance in real-time, dynamic IoT settings. This method achieves an optimal equilibrium between policy learning and optimisation, rendering it suitable for contemporary IoT systems. This method improves numerous IoT applications, including smart cities, industrial automation, and healthcare. The hybrid DQN-PPO-GNN-RL model addresses bottlenecks by dynamically managing computing and network resources, allowing for efficient operations in low-latency, high-demand environments such as autonomous systems, sensor networks, and real-time monitoring. The use of Graph Neural Networks (GNNs) improves the accuracy of resource representation, while reinforcement learning-based scheduling allows for seamless adaptation to changing workloads. Simulations using real-world IoT data on the iFogSim platform showed significant improvements: task scheduling time was reduced by 21%, operational costs by 17%, and energy consumption by 22%. The method reliably provided equitable resource distribution, with values between 0.93 and 0.99, guaranteeing efficient allocation throughout the network. This hybrid methodology establishes a novel benchmark for scalable, real-time resource management in extensive, data-centric IoT ecosystems, consequently enhancing system performance and operational efficiency.
