In this thesis, we introduce an approach to jointly minimizing energy consumption of wireless transmitters and the harmful interference on sensitive medical devices, and optimizing the central controller placement for collecting data from transmitters. More specifically, a multi-objective non-convex mixed-integer non-linear programming (MINLP) problem is defined and formulated to optimize transmit power of wireless users and CPP deployment along with guaranteeing minimized EMI to comply with the immunity level of medical devices. To solve this problem, an important step is to convexify it. Then we propose the use of a standard branch-and-bound algorithm. Also the program is coded in MATLAB with the help of OPTItoolbox to find the optimal solution. To conduct a numerical result analysis, we considered different cases within a single floor of a hospital and a few scenarios for a two-story hospital building. The values of different variables are changed throughout the simulation and the results are compared. These variables include immunity level of sensitive medical devices, maximum transmission power of wireless users, floor attenuation factor, etc. Our results show the improvement in throughput and guaranteed immunity for medical devices, when the proposed formulation is deployed along with a branch-and-bound algorithm.

“…For indoor applications, WOCs have been recently an active field of research thanks to their immunity toward RF ones, but also for the increase in the high data rates demand and the safe data transfer they provide [7–18]. In particular, for mobile health monitoring applications, previous studies have explored the performance of WOC between a central unit placed on a patient and a base station fixed in the indoor environment [13, 15]. We propose here to enlarge these investigations to the field of mobile BAN, by evaluating the performance of an on‐body link using WOC.…”

International audienceUsing wireless optical communication (WOC) to establish on-body links constitutes a promising solution to address radiofrequency interference issues in body area network (BAN) especially concerning medical applications. Actually, this permits decreasing electromagnetic perturbations in the patient body environment. To evaluate WOC performance for BAN scenario, the authors investigate on-body communication between a BAN node and the central unit placed on the patient which is supposed to be moving in a room. Considering a diffuse optical transmission scheme based on optical reflections over the environment, the authors propose an adapted, fast and simple method to determine the performance taking into account the presence of obstacles in the room. Thanks to this method, the authors evaluate the WOC outage probability assuming uniform node mobility on the patient body and patient mobility in the environment. The results permit discussing the WOC robustness according to the optical reflection properties of the blocking elements and show the WOC potentialities for mobile medical BAN scenario

“…For around 50 years, optical wireless communications have been investigated for different applications including short‐range indoor links or outdoor intra‐building and inter‐satellite uses [3–8]. The potentialities of using optical wireles communications in the infrared range for healthcare monitoring have already been investigated from a theoretical point of view [9–11]. Indeed, using optical wireless links permits reducing the amount of RF effects in the patient vicinity and ensures that there is no interference with existing RF and electronic equipment.…”

In this Letter the authors explore the communication capabilities of optical wireless technology for a wearable device dedicated to healthcare application. In an indoor environment sensible to electromagnetic perturbations such as a hospital, the use of optical wireless links can permit reducing the amount of radio frequencies in the patient environment. Moreover, this technology presents the advantage to be secure, low-cost and easy to deploy. On the basis of commercially available components, a custom-made wearable device is presented, which allows optical wireless transmission of accelerometer data in the context of physical activity supervision of post-stroke patients in hospital. Considering patient mobility, the experimental performance is established in terms of packet loss as a function of the number of receivers fixed to the ceiling. The results permit to conclude that optical wireless links can be used to perform such mobile remote monitoring applications. Moreover, based on the measurements obtained with one receiver, it is possible to theoretically determine the performance according to the number of receivers to be deployed.
