“…ALARP (Railway Automatic Track Warning System Based on Distributed Personal Mobile Terminals) [17] consists in studying, designing and developing innovative Automatic Track Warning Systems (ATWS) to improve the safety of railway trackside workers. Its main objective is to notify working gangs along train lines, alerting them of trains and other rolling stocks approaching the worksite [18].…”

“…Regarding point iv), the ALARP middleware includes a degraded state to address issues on time uncertainty and localization uncertainty. MT activates specific procedures to mitigate such uncertainties, increasing the resources devoted to the execution of the algorithms for clock synchronization and localization [18]. In HIDENETS, the QoS Coverage Manager service provides support for applications to adapt to the available QoS.…”

“…Low-cost GPS receivers are not sufficiently accurate to reliably identify if a worker is in a red or a green zone, as it was measured in [61]. A GPS-augmentation approach has been devised in ALARP, and it is presented and evaluated in [18]. In such approach, GPS data is combined with information provided by electronic fences (i.e.…”

Abstract-A dramatic shift in system complexity is occurring, bringing monolithic system designs to be progressively replaced by modular approaches. In the latest years this trend has been emphasized by the System of Systems (SoS) concept, in which a complex system or application is the result of the integration of many independent, autonomous Constituent Systems (CS), brought together in order to satisfy a global goal under certain rules of engagement. The overall behavior of the SoS, emerging from such complex interactions and dependencies, poses several threats in terms of dependability, timeliness and security, due to the challenging operating and environmental conditions caused by mobility, wireless connectivity, and the use of off-the-shelf components. Referring to our experience in mobile safety-critical applications gained from three different research projects, in this paper we illustrate the challenges and benefits posed by the adoption of an SoS approach in designing, developing and maintaining mobile safety-critical applications, and we report on some possible solutions.

Wearable devices have emerged in the last years with new applications that provide user convenience. Healthcare, sports, safety are some examples of applications embedded in thousands of devices released in the last years. Wearable operating systems with different focus emerged together with wearable applications in order to make adjustments and optimizations of software and hardware. This paper presents a wearable operating systems discussion and shows the current challenges and wearable operating system influence. We developed a wearable appliance for geology. The wearable contains a Head Mounted Display (HMD) assembled with Google Cardboard API and sensors connected to developments boards. For each system component was used different operating systems according to hardware and software available. The results indicate some trends for wearable operating systems.
