Mühendislik ve Doğa Bilimleri Fakültemizin düzenlediği webinar serisi kapsamında 21 Şubat Pazartesi saat 18.00’de Işık Üniversitesi’nden Dr. Farshad Miramirkhani“Channel Modeling and Characterization for VLC-based Medical Body Sensor Networks: Trends and Challenges” başlıklı bir sunum yapacak.

Zoom üzerinden gerçekleşecek etkinlik ilgilenen herkesin katılımına açıktır. 

Özet: It is estimated that around 70%-80% of the mobile data traffic takes place in an indoor environment. This requires the development of low cost, energy-efficient and high-speed indoor wireless access solutions. To release the pressure on highly congested radio frequency (RF) spectrum, visible light communications (VLC) has emerged as a complementary and/or alternative wireless access technology. VLC, also known as light fidelity (LiFi), is based on the principle of modulating light emitting diodes (LEDs) at very high speeds that are not noticeable by human eye. This lets the use of LED luminaires for wireless communication in addition to their primary function of illumination. Operating at optical bands with large bandwidth capacity, VLC can be utilized as a complementary technology where excess capacity demands of cellular or wireless fidelity (WiFi) networks can be offloaded. VLC can be also potentially used as an alternative in safety-critical and hostile environments such as hospitals, airplanes, petrochemical plants, mines where the use of RF is prohibited or partially restricted. The IEEE has established the standardization groups of the IEEE 802.15.13 (Short Range Optical Wireless Communications) and IEEE 802.11bb (Light Communications for Wireless Local Area Networking), which are currently in the process of developing a standard for VLC.

In this seminar, we focus on indoor VLC-based medical body sensor networks (MBSNs) which allow the LEDs to communicate between on-body sensors/subdermal implants and on-body central hubs/monitoring devices while also serving as a luminaire. As with any other communication system, realistic channel models are of critical importance for VLC system design, performance evaluation, and testing. In that respect, this seminar presents a realistic channel modeling approach called site-specific ray tracing that considers the skin tissue for the MBSNs channel modeling for realistic hospital scenarios.
