“…Therefore, a thorough evaluation and a detailed exploration of these novel concepts are strongly desired in an experimental setup. With an advanced progression in the design, the penalty of discovering a wrong design decision or an error in the drafted concept dramatically increases [20].…”

Today's RFID systems exhibit relatively little functionality, while future systems and ubiquitous computing applications require an ample set of general purpose features, like wide communication ranges, high data rates, high reliability, and many more. In order to meet these high-performance goals, several challenges in state of the art RFID systems need to be managed: (1) the compatibility of RFID equipment, working according to different standards in various frequency domains, (2) the thorough understanding of the performance impact of physical layer system parameters, (3) the venture of novel wireless technologies in the context of RFID, and finally, (4) to deal with the increased complexity of high-performance RFID systems. Therefore, designers desire a highly configurable, flexible, and high-performance RFID environment to experimentally explore the underlying physical conditions and to evaluate novel RFID technologies and designs. This paper introduces the concept of rapid prototyping in RFID and provides a survey of system simulators, demonstrators, and rapid prototyping environments. A guideline for the setup for such a rapid prototyping system applicable for RFID is presented, and its implementation is demonstrated. Finally, some exemplary measurements carried out with this rapid prototyping system are presented.

The continuously progressing technology scaling is not only the source for increasing performance and complexity of embedded systems, but also the reason for rising reliability concerns of the underlying hardware. Consequently, numerous techniques emerged in recent years to mitigate wide range of error causes. Single layer methods, though, proved to be limited in providing an effective and efficient way to address errors in the system perspective. This paper proposes the new technology Cross-Layer Error Verification, Evaluation and Reporting (CLEVER), which is capable of gathering errors and system information on different levels of abstraction to evaluate the remaining useful lifetime of the system and its current state. Thus, CLEVER permits to overcome errors due to time-dependable and abrupt deterioration effects in complex embedded systems with a reasonable overhead. The presented system architecture was designed using a system description language and integrated in a simulation platform. Simulation results indicate the feasibility of this technology.

“…The SAOVR electronics package is built on the guest PC's XP system. From a technical perspective, this is not as desirable as a real time operating system (RTOS) in terms of performance guarantees (Janka ), but it allowed the use of the Windows serial RS232 COM library and the Windows threading and synchronization libraries, as well as the C++ Standard Template Library (STL). The embedded Windows PC was also already required to run the hydrophone/processor's native interface software (MAPHost).…”

Autonomous underwater vehicles (AUVs) have demonstrated superior performance for tracking marine animals tagged with individually coded acoustic transmitters. However, AUVs engaged in mapping the distribution of multiple tagged fish have not previously been able to alter search paths to achieve precise position estimates. This problem is solved by the development of payload control software (Synthetic Aperture Override, SAOVR) that allows the AUV to maneuver with trajectories favorable for solving the tag's location from a synthetic aperture. Upon tag detection during a default mission search path, SAOVR (running on an embedded guest computer) seeks permission to take over navigation from the vehicle's native system after checking constraints of geography, timing, tag identification, signal strength, and current navigation state. Permitted maneuvers are then chosen from a template library and executed before returning the AUV to the point of first deviation for continued searching of other tags. Field evaluation on moored reference tags showed a high level of predictability in the AUV's behavior at SAOVR initiation and through maneuvers. Trials suggest that this logic system is highly beneficial to AUV use for fish telemetry in challenging environments such as narrow, deep fjords, or among reefs. Any mission programmed with the AUV's native software can be run with the SAOVR package to allow scientists to easily implement and manipulate synthetic aperture geometries without altering any of the software. Further modeling can help improve template design specific to expected movements of different fish species and relative to the designation of signal strength-defined execution thresholds.
