Blockchain is one of the most promising technologies which supports the concepts of decentralization and provides secure solutions across the fields. However, implementing reliable and efficient security and data consistency in real-time, high-risk domains is still an active research issue due to the ever-growing number of cyber threats and complex characteristics of large-scale distributed systems. Some of the problems that are prevalent in current blockchain environment include; fault tolerance, scalability and anomaly detection. Encouraged by these gaps, this research presents PhyBb-WBS: Physics-Infused Framework for Enhancing Decentralized Security and Data Credibility of Blockchain-Based distributed Apps. This framework implements the Fault Tolerant Consensus via Weighted Byzantine Strategy to achieve resilient and robust consensus, the Physics Infused Deep Neural Networks for anomaly detection and the Multimodal Bowerbird Optimization for dynamic parameters optimization providing a security solution robust in the face of such challenges. Specifically, the principal goal is the development of a reliable and, at the same time, practically oriented blockchain structure capable of meeting real-time requirements for data protection and storage. Originally, the framework is tailored for the applications like energy trading and transactions that require high quality of network. Performance evaluations demonstrate significant advancements, achieving over 99.8% anomaly detection accuracy and fault tolerance rates surpassing 99.5%. Additionally, it enhances throughput by 99.25% compared to traditional optimization methods. In conclusion, this paper presents the PhyBb-WBS framework that helps to improve the security and viability of blockchain. Solving important problems by leveraging sophisticated consensus protocols, effective anomaly detection, and adaptive optimization, this research proposes a significant advancement in utilizing decentralized systems in high-stake

The ever-growing complexity of IoT networks ignited by their wide scale adoption in applications such as smart cities, the industrial automation, and health care, compelled to develop sophisticated yet resource efficient and scalable network management solution. Centralized systems are traditional in architecture, which leads to higher latency and bottlenecks, while decentralized systems can distribute workloads however the lack of adaptability to real time, along with the difficulty of extracting maximum resource usage, are limitations. In recent years, reinforcement learning (RL) based approaches have taken shape as a promising alternative to facilitate the automated learning and optimisation of task management. However, there are two challenges for existing RL based methods: slow convergence, inefficient priority assignment of tasks, and poor coordination amongst agents in the case of dynamic, large scale IoT environment. To solve these challenges, in this research we propose a distributed reinforcement learning based multi agent framework for managing IoT network. The framework also integrates a task prioritization mechanism to dynamically choose an optimal task allocation solution. Further validation was performed in a simulated IoT environment where real world inspired datasets were used. The proposed framework demonstrated 30% more task throughput than centralized, 25% less latency than decentralized, and 40% more energy efficiency than current RL based systems. The system was further validated using advanced visualizations such as anomaly detection maps and resource allocation efficiency graphs, demonstrating its capacity to manage dynamic load of tasks and resource allocation. The proposed framework addresses the critical limitations of current methods, through scalable, adaptive, and energy efficient framework for managing IoT network, and accordingly helps advancing the intelligent and autonomous IoT systems.

A challenge for the distributed systems community is to build simple yet flexible environments for composing applications from service components. We need to make the art of software composition available to a broader range of software architects rather than solely technical specialists. Software components are inherently heterogeneous and require infrastructure support for their entire lifecycle of creation, incorporation, alteration, and demise. The ODSI architecture supports the specification and execution of heterogeneous service collaborations based on a shared enterprise model and event-based management infrastructure.

This paper presents and discusses some infrastructure services necessary for distributedapplications development. The main service considered is the component search service which includes traditional naming and trading-like services. A number of studies have shown recently that current trading, based on interface type conformance, is insufficient for component-based applications. These studies have conclude that semantic information, describing especially the behavior of the component and its context dependencies, is required. This type of trading is called semantic trading. In this paper, we address this problem and propose a component search service model based on semantic trading. Furthermore, we discuss the integration of the service in a deployment tool, through an enhanced deployment process early proposed by Corba Component Model.

The Eternal system provides CORBA applications with robust fault tolerance and the ability to be upgraded without a service interruption. The Eternal Evolution Manager handles both interface-preserving upgrades and interface-changing upgrades. The syntax and semantics of the application objects' IDL interfaces are unchanged by an interface-preserving upgrade. Interface-changing upgrades allow modification to one or more application object's IDL interfaces. Because modification to an object's IDL interface can affect clients of that object, an interface-changing upgrade requires coordinating the upgrade of multiple application objects at the same time.

objects are replicated in order to increase reliability and availability of an object-based system. We discuss how to invoke methods on replicas of objects in a nested manner. If a method t is invoked on multiple replicas and each instance of t on the replicas invokes a method u on another object y, u may be performed multiple times on some replica of y and then the replica gets inconsistent, i.e. redundant invocations. In addition, if each instance of t issues a request to a quorum, more number of the replicas are manipulated than the quorum number of the method u, i.e. quorum explosion. We discuss an invocation protocol to resolve the redundant invocation and quorum explosion. We evaluate the protocol on how many replicas are manipulated and requests are issued.

Numerous technical and life cycle cost consideration trends have led to a large increase in the use of commercial, off the shelf (COTS) computing and networking infrastructure in military command and control (C2) applications. Object oriented (OO) real-time middleware, such as RT CORBA, provides the capabilities required for domain specific services and applications. However, it is unproven whether such commercial technologies can achieve the hard real time performance required by many C2 system. Our study reveals that DOC middleware is suitable for some real-time applications when appropriately coupled with operating system and network protocol quality of service (QoS) mechanisms areas in which further progress is still needed.

distributed object technologies offer access to data and services virtually everywhere in a distributed application system and introduce a high degree of freedom in application design. In order to retain flexibility even during business process re-engineering, the explicit modelling of business process aspects separately from the application system components is desired. The most prominent technology to serve this purpose is workflow management, which is a groupware technology and mainly focuses on the collaboration of people. Recently developer of distributed object platforms start to provide services that initially aimed at managing distributed transactions but also allow for the modelling and enactment of communication sequences between distributedobjects. We have applied the workflow management approach practically within a heterogeneous laboratory environment integrating typical radiology application systems. Here, we compare our experiences with what can be expected from such a distributed object platform taking Microsoft's BizTalk as example.
