Adaptive Internet Integration of Field Bus Systems

Field buses are used to network sensors, actuators, and control devices inside automation systems. The Internet integration of field bus systems enables information from these devices to be exchanged across enterprises and businesses. An essential prerequisite to this aim is the interoperability of field bus systems with external systems and applications. Therefore, many efforts are made to establish a common information exchange standard which all field bus systems are supposed to support. However, the longer these efforts are ongoing the less it seems that they will ever yield the expected breakthrough. The present paper introduces an substantially different approach to interoperability. Field bus systems may keep their individual application interfaces and data exchange formats. All the same, external infrastructures do not have to be redesigned to match the specific needs of certain field bus systems. Rather, field bus systems become capable of adapting the information exchange flexibly according to the needs of the outside environment

Interoperability Verification in ISO 18000-7 Active RFID Systems: Experimental Setup and Results

Interoperability in an RFID system conforming to ISO 18000-7 standard is defined as the ability of any commercial interrogator to communicate with any commercial tag. A possibility that conformance verification in the physical communication layer between active tags and interrogators (readers) does not satisfy the interoperability property is established. Challenging the traditional or matrix test to verify interoperability, a novel methodology to verify interoperability for active RFID systems in particular and all communication systems following a command-reply protocol in general is introduced in a prior publication. In this article, the methodology is experimentally implemented using industry standard laboratory equipment and automation tools to develop a fully automated interoperability test suite. The automated test system design considerations, challenges and results are discussed in detail. For a particular equipment, the NI-5671 Radio Frequency Signal generator, the maximum number of samples that can be tested for different parameters of the physical communication layers are provided. The equipment limitations are discussed to provide the reader with guidelines to experiment with, and a reference to evaluate the resolution (one measure of the accuracy of the test) of different equipment. The different parameters considered in the test and their interactions in determining the interoperability property are recorded.

A wearable point-of-care system for home use that incorporates plug-and-play and wireless standards.

A point-of-care system for continuous health monitoring should be wearable, easy to use, and affordable to promote patient independence and facilitate acceptance of new home healthcare technology. Reconfigurability, interoperability, and scalability are important. Standardization supports these requirements, and encourages an open market where lower product prices result from vendor competition. This paper first discusses candidate standards for wireless communication, plug-and-play device interoperability, and medical information exchange in point-of-care systems. It then addresses the design and implementation of a wearable, plug-and-play system for home care which adopts the IEEE 1073 Medical Information Bus (MIB) standards, and uses Bluetooth as the wireless communication protocol. This standards-based system maximizes user mobility by incorporating a three-level architecture populated by base stations, wearable data loggers, and wearable sensors. Design issues include the implementation of the MIB standards on microcontroller-driven embedded devices, low power consumption, wireless data exchange, and data storage and transmission in a reconfigurable body-area network.     

Interoperability Test Methodology for ISO 18000-7 Active RFID

Standards are developed by highly reputed organizations with a genuine intention that the document acts as a reference requirement and specification record for all manufacturers, and in this process the consumer is presented with a list of conforming products that are all interoperable. Active RFID tags and readers are designed with commercial intent by different manufacturers according to the ISO 18000-7 standard. Through intensive research and tests, it has come to our attention that it is possible to design two active RFID systems that in their entirety conform to the ISO 18000-7 standard and yet be not interoperable with each other. From this statement it can be inferred that conformance is not the sufficient condition for interoperability as is popularly believed, but only the necessary or minimum condition to satisfy interoperability. Therefore apart from preliminary conformance testing, it becomes absolutely essential to include additional and supplemental interoperability tests into the verification process of the production cycle. This research primarily establishes the requirement for interoperability testing giving instances where the standard fails to insure interoperable products. The traditional method to test interoperability currently in practice are investigated and their limitations are exposed. Further this research paper introduces an innovative and ingenious methodology to test active RFID systems for interoperability at the physical layer.     

TMN-based broadband ATM network management

ATM has rapidly transitioned from a standards and prototyping concept to become the next-generation switching technology used in products available on the market. With the rapid introduction of ATM switches into networks, there is an urgent need to manage them. The article discusses the telecommunication management network (TMN) interfaces being defined for management systems to communicate with ATM network elements (NEs) and other management systems. ATM management systems will have to communicate with ATM NEs in their jurisdiction using TMN interfaces. Networks will usually contain equipment from different suppliers. Thus, it is vital that there be standard management interfaces so that these different NEs can be managed. Some standard interfaces for ATM networks are defined, while others are being defined. The status of these interfaces is reviewed in the article. Communication between different networks is also needed, both between public networks and between public and private networks. Management personnel of one network need to exchange information with other networks for certain functions (e.g., initial service provisioning), and so management systems of different networks will exchange information through a combination of mechanized and manual interfaces. The status of these interfaces is also reviewed in the article
