Fault-Tolerant Membership Service in a Synchronous Distributed Real-Time System

Abstract: In many hard real-time applications, timely knowledge about the operational state of the nodes in a distributed computer system is of significant importance. This paper presents a fault-tolerant distributed membership protocol for the determination of the set of active nodes in a synchronous distributed real-time system. After a discussion of the system architecture and the fault hypothesis, which is supported by experimental data, the membership protocol is described in detail. In the final section the application of this protocol for the design of selfchecking nodes, for the solution of the atomic multicast problem and for the remote monitoring of nodes is discussed.

Optimized dynamic storage of data (ODSD) in IoT based on blockchain for wireless sensor networks

Abstract: The Industry 4.0 IoT network integration with blockchain architecture is a decentralized, distributed ledger mechanism used to record multi-user transactions. Blockchain requires a data storage system designed to be secure, reliable, and fully transparent, emerged as a preferred IoT-based digital storage on WSN. Blockchain technology is being used in the paper to construct the node recognition system according to the storage of data for WSNs. The data storage process on such data must be secure and traceable in different forensics and decision making. The primary theme of the dynamic data security is therefore for rejecting exploitation of the unauthorized user and for evaluating the mechanism in tracing and evidence of system’s data operation in a dynamic manner, growth and quality features under the stochastic state of the model; (1) a mathematical method for the secured storage of data in dynamic is built through distributed node cooperation in IoT industry. (2) the ownership transition feature and the dynamic storage of data system architecture are configured, (3) the emerging distributed storage architecture for blockchain-based WSN will substantially reduce overhead storage for each node without affecting data integrity; (4) minimize the latency of data reconstruction in distributed over storage system, and propose an effective and scalable algorithm for optimizing storage latency issue. In addition to this research, the system implements verified possession of data for replacing the evidence in original digital currency for mining and to store new data blocks that will be compared to the proof system, dramatically reduces computational capacity. The proposed ODSD framework has exceptional benefits for real-time applications while maintaining the security of the dynamic storage of data.

Hyperspeech: navigating in speech-only hypermedia

Abstract: Most hypermedia systems emphasize the integration of graphics, images, video, and audio into a traditional hypertext framework. The hyperspeech system described in this paper, a speech-only hypermedia application, explores issues of navigation and system architecture in an audio environment without a visual display. The system under development uses speech recognition to maneuver in a database of digitally recorded speech segments; synthetic speech is used for control information and user feedback. In this research prototype, recorded audio interviews were segmented by topic, and hypertext-style links were added to connect logically related comments and ideas. The software architecture is data driven, with all knowledge embedded in the links and nodes, allowing the software that traverses through the network to be straightforward and concise. Several user interfaces were prototype, emphasizing different styles of speech interaction and feedback between the user and machine. In addition to the issues of navigation in a speech-only database, areas of continuing research includtx dynamically extending the database, use of audio and voice cues to indicate landmarks, and the simultaneous presentation of multiple channels of speech information.

Croquet - a collaboration system architecture

Abstract: Croquet is a computer software architecture built from the ground up with a focus on deep collaboration between teams of users. It is a totally open, totally free, highly portable extension to the Squeak (Ingalls et al., 2002) programming system. Croquet is a complete development and delivery platform for doing real collaborative work. There is no distinction between the user environment and the development environment. Croquet is focused on interactions inside of a 3D shared space that is used for context based collaboration, where each user can see all of the others and what their current focus is. This allows for an extremely compelling shared experience. A new collaboration architecture/protocol called TeaTime has been developed to enable this functionality. The rendering architecture is built on top of OpenGL (Woo et al., 1999).
