We present a viable communication infrastructure and protocols to support the versatile data exchange in a network of smart cameras. Each node in network is an embedded smart camera whose hardware/software architecture was carefully designed to meet the performance requirement while providing sufficient flexibility. We introduce a novel scalable clustering approach, which uses asynchronous event exchange...
This paper describes a middleware layer for soft real-time communication in wireless networks devised and realized using standard WLAN hardware and software. The proposed middleware relies on a simple network architecture comprising a number of stations that generate real-time traffic and a particular station, called Scheduler, that coordinates the transmission of the real-time packets using a polling...
The DMW(Data-Centric Middleware) in CPS to support for high reliable and Autonomous Controlling Software is the platform that distributes a Publish/Subscribe based real-time data and supply a different QoS(Quality of Service). This paper deals with the DTB(Data Transport Block) in DMW that is to supply high reliable and QoS.
We describe our implementation of a novel deep ocean sensor network, the MBARI Free Ocean CO2 Enrichment (FOCE). FOCE is a system designed for installation in the deep ocean to enable manipulative experiments that explore the impact of deep ocean increase in CO2 and resulting pH change on ocean biogeochemistry and ecology. This system uses control feedback and pH sensors to inject CO2 into a small...
The cognitive radio technology is very helpful in improving the use of spectrum resources and reacting its operating environment. This paper presents a novel embedded framework for secondary user based a single FPGA in cognitive network. By analyzing the processing ability of FPGA and evaluating the existed architecture, this framework based FPGA supplying more logic resources and stronger embedded...
Most of message-oriented middleware of distance teaching platform are centralized message-oriented middleware (MOM) based on C/S model. The clients interact with each other through center messaging servers. The disadvantages of traditional centralized MOM, such as single-point congestions and single-point failures, decrease the communication efficiency greatly. In this paper, we design a novel MOM...
Our work provides the specification and implementation of a communication mechanism between broadcast content viewers and interaction devices or sensors placed on the scenario of a live video show. This solution was designed using middleware based architecture and interconnects the devices and sensors of a broadcast program environment in a device network. By using the proposed architecture, the viewers...
Even though smart home technology is becoming more common, there has been little research about upgrading existing systems; yet, as smart homes become more common, the coexistence of different technologies is to be expected. To study these issues, we have updated our previous smart home architecture to support our service discovery enabled EPIS network protocol. The new middleware is designed to enable...
This paper deals with the problem of improving the tailorability and extensibility of current Learning Management Systems by allowing them to use third-party tools. Nowadays there are several initiatives to integrate in e-Learning systems tools deployed by external providers following the Software as a Service distribution model. However, these initiatives achieve at best a very “soft” integration...
As the Home Area Network (HAN) evolves, there is an increase in both the number and diversity of device deployment. This includes embedded devices whose resource constraints do not permit the efficient performance of high level middleware functionality. We herein present the functionality and knowledge representations required to enable such “simpleware” devices to be dynamically represented by proxy...
Radio Frequency Identification technology is an emerging technology that allows objects to be electronically tagged and identified wirelessly. In recent years, many organizations have started to show interest in porting this technology to their existing business processes. With the increase in popularity of the technology, many vendor-specific RFID readers are being manufactured and sold to interested...
Serious problems we face within avionics development of every new spacecraft are: the huge cost and long development time due to the interfaces specification, which has to be written and specified for every satellite from scratch. Furthermore we must consider the extremely high costs and almost no post-development reuse of the board computer. Our strategy is what we call network centric computing...
Extensible Messaging and Presence Protocol (XMPP) is an open, XML-based protocol aimed at near-real-time, extensible instant messaging (IM) and presence information. It has been expanded into the broader realm of message-oriented middleware. Built to be extensible, the protocol has been extended with features such as Voice over IP and file transfer signaling. XMPP protocol has been used by many social...
Middleware has been extensively used in mobile devices to abstract issues raised by mobility, such as resource constraints, intermittent connectivity and platform variability. In such a sense, several proposals that explore mobile middleware concerns can be identified in the literature. However, in general, most of them deal with specific aspects of mobility (e.g. distribution, context, adaptation),...
RFID device management and monitoring is an indispensable part of RFID middleware technology, this paper presents an implementation of device management and monitoring in reconfigurable middleware, which consists mainly of two tasks: one is managing the RFID hardware and software devices, and the other is monitoring the running status of RFID software and hardware devices. Through management, we can...
The widespread adoption of broadband Internet connections and the need of institutions such as universities or enterprises to provide their staff with continuous education have led to a fast adoption of Learning Management Systems. These systems typically provide a centralized environment where students can communicate, carry out experiments, etc. However, the rapid growth of these platforms together...
Event driven architectures are widely used in numerous software applications, for instance in GUI focused software. Currently most event driven softwares are applied merely in local environment. If we need to use event driven architecture in a distributed environment, there are not too many candidates to choose from. Thus, although there are a number of techniques which support the event notification...
Collaborations by the use of inter-organizational business processes can help companies to achieve a competitive edge over competing businesses. Typically, these collaborations require an efficient identity management (IdM) that ensures the authorized access to services in different security domains. The successful implementation of an IdM in distributed systems requires to cope with a diversity of...
The Wireless Sensor Networks (WSN) environments are increasingly becoming intelligent with the rapid boost in the capabilities of sensor nodes. The Sun Small Programmable Object Technology (SPOT) platform offers a high-end sensing device in terms of processing, memory and battery configurations compared to other existing in the community. Within the scope of this paper, a health care use case is derived...
Virtualization is an effective mean of supporting the new internet architecture research,The ForCES idea of control element and forwarding element separation provide a basis for router virtualization. This paper focus on the research of virtual service application implement base on the ForCES framework, we built a virtual service application architecture based on the ForCES framework in PC, this system...
