“…4. These patient monitors from Medlab have been used in a previous mHealth project [23], as they monitor multiple vital signs, from non-invasive blood pressure (NIBP) to pulse-oximeter and heart rate. These modules have also been extended with a version of Movital in the communications box (A), which includes the 6LoWPAN transceiver by Jennic (B), and a RFID reader to identify patient/nurse (C).…”

Communication and information access defines the basis to reach a personalized health end-to-end framework. Personalized health capability is limited to the available data from the patient. The data is usually dynamic and incomplete. Therefore, it presents a critical issue for mining, analysis and trending. For that reason, this work presents an interconnection framework for mobile Health (mHealth) based on the Internet of Things. It makes continuous and remote vital sign monitoring feasible and introduces technological innovations for empowering health monitors and patient devices with Internet capabilities. It also allows patient monitoring and supervision by remote centers, and personal platforms such as tablets. In terms of hardware it offers a gateway and a personal clinical device used for the wireless transmission of continuous vital signs through 6LoWPAN, and patient identification through RFID. In terms of software, this interconnection framework presents a novel protocol, called YOAPY, for an efficient, secure, and scalable integration of the sensors deployed in the patient's personal environment. This paper presents the architecture and evaluates its capability to provide continuous monitoring, ubiquitous connectivity, extended device integration, reliability, and security and privacy support. The proposed interconnection framework and the proposed protocol for the sensors have been exhaustively evaluated in the framework of the AIRE project, which is focused on patients with breathing problem. This evaluates for the proposed protocol the data aggregation mechanism level, Round-Trip delay Time, impact of the distance, and the impact of the security. It has been concluded that secure continuous monitoring is feasible with the use of the proposed YOAPY aggregation mechanisms and the capabilities from the proposed interconnection framework.

“…Several projects have focused on the deployment of OWCs in aircraft. These projects have generally focused on cabin communications as in-flight connectivity can offer new services to passengers [7]- [12].For example, the studied scenarios included entertainment applications [7], video broadcasting [8], communication between passengers [9], and even medical surveillance [10]. One of the main challenges in the context of an aircraft is to ensure adequate coverage of the cabin environment, which requires a thorough analysis of the communication channel [11].…”

Communications inside an aircraft cockpit are currently based on wired connections especially for the audio headsets used by the pilots. A wireless headset would be an advantage in terms of comfort and flexibility but the use of classical radio frequencies is limited by interference and security issues. Optical wireless communication technology is an option for headset connectivity. Indeed, as optical beams are confined, this technology provides robustness against the risk of hacking, thus increasing security. In addition, the use of optical waves ensures the absence of radio-frequency disturbances. Using simulation, this paper presents a thorough study of the optical wireless channel behavior inside the cockpit of an aircraft by considering a headset worn by a pilot possibly in motion and an access point at the ceiling. The impact of the characteristics of the environment model, such as the level of geometric description, the reflectivity of materials and for the first time, the ambient noise induced by the sun, is highlighted. System performance is evaluated in terms of optimal half-power angles and the necessary average optical power of the light sources.

In this article, we explore the performance of optical wireless technology for ensuring audio communications inside an aircraft cockpit. One advantage is that, unlike radio frequencies, opaque objects block optical signals and, therefore, signals cannot pass through walls. This can reduce security risks against eavesdropping and hacking of the physical layer, which is one of the main concerns in the aviation environment. However, optical wireless technology faces some issues, including range limitation and sensitivity to blockages. To study the achievable performances, we propose a modeling of the channels for the uplink and the downlink between the headsets of the four pilots of an Airbus A350 and the access point at the cockpit ceiling. A ray-tracing approach associated with a Monte-Carlo method takes into account the 3D geometric model of the cockpit, the presence of the pilots and their movements. We show that using spatial diversity for headset transceivers can improve performance. Using IEEE 802.11 medium access control mechanism to ensure multiuser communication, the approach highlights the trade-offs between power and delay for a successful communication, linked to the maximum achievable data rate for a given performance level.
