Distributed Simulation Using DDS and Cloud Computing

NASA Langley Research Center identified a need for a distributed simulation architecture that enables collaboration of live, virtual, and constructive nodes across its local area network with extensibility to other NASA Centers and external partners. One architecture that was prototyped and evaluated employed Data Distribution Service (DDS) middleware and the GovCloud cloud computing service. The nodes used DDS to exchange data.

An investigation into some security issues in the DDS messaging protocol

The convergence of Operational Technology and Information Technology is driving integration of the Internet of Things and Industrial Control Systems to form the Industrial Internet of Things. Due to the influence of Information Technology, security has become a high priority particularly when implementations expand into critical infrastructure.

Retargeting Embedded Software Stacks for Many-Core Systems

As recent technology trends usher us into the many-core era, software applications must scale as 1000s core become available in a single chip. Middleware is a key infrastructure component between applications and the operating system. Therefore, new middleware mechanisms must be developed to handle scheduling, resource sharing, and communication on platforms with 100s and 1000s of cores. The solution must help application developers create concurrent software and must be easy to use.

A QoS Policy Configuration Modeling Language for Publish/Subscribe Middleware Platforms

ABSTRACT: Publish/subscribe (pub/sub) middleware platforms for event- based distributed systems often provide many configurable policies that affect end-to-end quality of service (QoS). Although the flexibility and functionality of pub/sub middle- ware platforms has matured, configuring their QoS policies in semantically compatible ways has become more complex.

Evaluating the Performance of Publish/Subscribe Platforms for Information Management in Distributed Real-time and Embedded Systems

Abstract: Recent trends in distributed real-time and embed- ded (DRE) systems motivate the development of infor- mation management capabilities that ensure the right information is delivered to the right place at the right time to satisfy quality of service (QoS) requirements in heterogeneous environments.

Self-describing and Data Propagation Model for Data Distribution Service

Abstract: To realize real-time information sharing in generic platforms, it is especially important to support dynamic message structure changes. For the case of IDL, it is necessary to rewrite applications to change data sample structures. In this paper, we propose a dynamic reconfiguration scheme of data sample structures for DDS. Instead of using IDL, which is the static data sample structure model of DDS, we use a self describing model using data sample schema, as a dynamic data sample structure model to support dynamic reconfiguration of data sample structures.
