A polystore system is a database management system composed of integrated heterogeneous database engines and multiple programming languages. By matching data to the storage engine best suited to its needs, complex analytics run faster and flexible storage choices helps improve data organization. BigDAWG (Big Data Working Group) is our prototype implementation of a polystore system. In this paper,...
To support next-generation power grid monitoring, protection, and control, we re-view and synthesize the new requirements and challenges of the enabling data architecture. We outline the necessary elements and a framework for the data architecture including the data path, synchronization and alignment layer, high-speed stream processing, databases, data service layer, and the interaction with analytics...
Node.js is one of the better-known frameworks and environments that support server-side JavaScript development. Many frameworks provide a full-featured Web stack, such as Connect and Express. Finally, many libraries available for client-side JavaScript that were written to comply with the Common JS module system also work with Node. In my work, we leverage node.js platform to construct a 3D theatre...
Combining robotic architectures with cyber systems has enormous potential for future robotic applications because it enables the possibility of online sharing of all aspects of the robotic architecture: the knowledge contained in architectural components, the parameterization of these components, the very component algorithms, as well as the architectural layout. In this paper, we discuss the potential...
Fully automated provisioning and deployment in order to reduce the costs for managing applications is one of the most essential requirements to make use of the benefits of Cloud computing. Several approaches and tools are available to automate the involved processes. The DevOps community, for example, provides tooling and artifacts to realize deployment automation on Infrastructure as a Service level...
This paper proposes a self-organizing framework for adapting software agents on complex computer systems, in particular distributed systems. It is unique to other existing approaches for software adaptation because it introduces the notions of differentiation and dedifferentiation in cellular slime molds into complex computer systems. When an agent delegates a function to another agent. the former's...
At a time when socialism as an economic option is variously questioned, very few people are against social instances of our life such as entertainment, customer assistance, and so on. This happens with the management of many things accompanying our life as well. We can find both the reason and the evidence for the viability of this trend in one very basic fact: things are social because they work...
This paper used middleware technology, using the network as the carrier of information, integrated the three-layers C/S software structure model into the manageable multi-layer software architecture, and used this architecture to construct a communication network real-time monitoring system that has good real-time performance, stability, and scalability.
This paper discusses characteristics and merits of three-tiered architecture in the system application, points out the core idea of three-tiered architecture is the distribution of calculation and data. This Paper put forward a basic principle that the middle tier should be a buffer of other tiers and the balance point of all loads, and it should be expanded for future business requirements. Based...
As scientific workflows are becoming more complex and apply compute-intensive methods to increasingly large data volumes, access to HPC resources is becoming mandatory. We describe the development of a novel plug in for the Tavern a workflow system, which provides transparent and secure access to HPC/grid resources via the UNICORE grid middleware, while maintaining the ease of use that has been the...
In this paper we present a distributed event driven middleware architecture for situational awareness and intelligent decision making for command and control of geographically distributed networked battlefield agents. We tackle the important and challenging issues of distributed agents scheduling, synchronization, load balancing, and terrain database distribution/management/allocation in a distributed...
With the recent technology and work done in the area of Wireless Sensor Networks (WSNs) it's becoming an emerging technology which could be used for sensing tasks in industrial automation, personal healthcare and information systems as well. The growth of wireless networks, applications and sensors over the last few years has been tremendous. These days' consumers begin to do their business, banking...

Middleware for wireless sensor and actor network is hard to design because the leverage between the hardware limitation and system complexity. Complex event processing middleware for wireless sensor network is proposed to solve this dilemma. The system utilized the computing power of the network nodes to reduce the network communication data, so that it can save the nodes' energy. The events processing...
Middleware design for wireless sensor network is a novel approach to solve the complexity of the development and deployment of the wireless sensor network applications. Complex event processing system for wireless sensor network is proposed and evaluated. The system utilized the computing power of the network nodes to reduce the network communication data, so that it can save the nodes' energy. The...
Sensor networks consist of various sensors and have a constraint depend on its physical characteristics. The sensor network middleware can provide with abstractions of characteristics about each sensor network to user applications. Thereby, these sensor networks can cooperate easily with traditional network through sensor network middleware platform. In this manner, agents in platform interact with...
Integration is playing an effective role in increasing revenues of enterprise systems. Heterogeneous operating systems, applications and RDBMS, inadequate of internet solutions, incompatible data format, application changes overtime and network problems are the main obstacles that should be taken in consideration in the process of integrating e-business applications. XML is the W3C standard language...
Along with the rapid improvement of the test instruments capability and network technology, the resources sharing and collaborative work implementing in test system have been in front us. In order to solute these problems, a novel network test system based on web service (NTSWS) is presented. In this paper, we elaborate the architecture and working mechanisms of the NTSWS system. Then, the system...
