- This paper presents a time synchronized wireless ECG sensor network with reliable data communication. Wireless ECG systems are a popular research area where several research groups have presented point-to-point solutions. Alongside the wireless ECG research, the wireless sensor network research has created an increasing interest for secure, low power and predictable network applications. Combining these research areas is a natural step for the evolution of secure wireless monitoring of physiological parameters. In this study the Bluetooth radio standard has been chosen for its versatility. This paper focuses on both the hardware and the software development for a functional multihop ECG network using Bluetooth. The presented wireless ECG network is reliable up to link loss and is easily configured to send more or different types of signals. The system has been tested and verified for secure multihop communication.

- In this paper a measurement system to create an experimental model and a tool box for simulations concerning both the energy consumption and the time aspect when creating wireless sensor networks using Bluetooth 2.0 + enhanced data rate has been developed. Further energy and time characteristics for critical events when using Bluetooth 2.0 in wireless sensor networks are investigated experimentally, with the main events; create connection, send data, receive data, and idle state. Results show that when allowing higher latencies for the connection in the Wireless Sensor Networks the power consumption drops drastically when using low power mode as sniff.

Konferensbidrag (refereegranskat)abstract
- Safety-critical systems are subject to rigorous assurance and certification processes to guarantee that they do not pose unreasonable risks to people, property, or the environment. The associated activities are usually complex and time-consuming, thus they need adequate support for their execution. The activities are further becoming more challenging as the systems are evolving towards open, interconnected systems with new features, e.g. Internet connectivity, and new assurance needs, e.g. compliance with several assurance standards for different dependability attributes. This requires the development of novel approaches for cost-effective assurance and certification. With the overall goal of lowering assurance and certification costs in face of rapidly changing features and market needs, the AMASS project has created and consolidated the de-facto European-wide open solution for assurance and certification of critical systems. This has been achieved by establishing a novel holistic and reuse-oriented approach for architecture-driven assurance, multi-concern assurance, and for seamless interoperability between assurance and engineering activities along with third-party activities. This paper introduces the main elements of the AMASS approach and how to use them and benefit from them.
