—Data collection has always been a major challenge in sensor networks and various techniques have been proposed to enable efficient data collection. One such methodology is the use of mobile elements within the existing infrastructure to enable data collection. The paper proposes the use of existing mobile elements like mobile phones which have enough spare(More)
—The number of small embedded devices connected to the Internet is increasing. This growth is mostly due to the large number of Internet of Things (IoT) deployments, with applications such as: industrial monitoring, home automation, and others. One common aspect with the majority of application areas is the lack of mobility. Most IoT devices are stationary(More)
—The last years we are witnessing of rapid advances in the industrial automation domain, mainly driven by business needs towards agility and supported by new disruptive technologies. Future factories will rely on multi-system interactions and collaborative cross-layer management and automation approaches. Such a factory, configured and managed from(More)
—The initiative AESOP (ArchitecturE for Service-Oriented Process-Monitoring and-Control) envisions a Service-oriented Architecture approach for monitoring and control of Process Control applications (batch and continuous process). Large process industry systems are a complex (potentially very large) set of (frequently) multidisciplinary , connected,(More)
A large number of potential applications for Wireless Sensor and Actuator Networks (WSAN) have yet to be embraced by industry despite high interest amongst academic researchers. This is due to various factors such as unpredictable costs related to development, deployment and maintenance of WSAN, especially when integration with existing IT infrastructure(More)
—A performance evaluation of a level-crossing analog-to-digital converter (ADC) is presented. It is shown that its signal-to-noise ratio (SNR) does not depend on the input-signal amplitude, which results in an almost-flat SNR for amplitudes that fall into the Nyquist criteria for irregular sampling. The influence of the reconstruction procedure on SNR is(More)
In a SOA-based system the applications are organized in a manner such that interoperable services can be used from different domains. In a process industry context, different domains can refer to, for example, process instrumentation and monitoring, execution of process control, data acquisition, etc. Large process industry systems are a complex and(More)
This paper describes a system where Internet-enabled sensor technology was integrated into a context-aware platform to give viewers of sport events an enriched media experience. The system was developed as a proof of concept and was evaluated during real-life use at the Vasaloppet crosscountry ski event. Using Bluetooth wireless ad-hoc networking and GPRS(More)
