Video on Demand Over Optical Wireless Communication Links

Abstract

Video on demand technology is a modern wireless communication application which requires a large bandwidth. Optical wireless networks, as a potential alternative to radio frequency, is an emerging technology that is easier to set up and provides a cost effective solution, where a physical network is difficult to deploy. Optical wireless networks can be used as a backbone to provide the much needed bandwidth for video on demand application. In this paper, Wavelength Division Multiplexing modulation scheme is proposed for the optical wireless networks due to its significance of transmitting distinct data channels at different wavelengths. Wavelength Division Multiplexing can be easily integrated with optical wireless networks, consequently resulting in an increased data rate. This paper presents a novel approach of integrating video on demand with the state of art Wavelength Division Multiplexing based optical wireless networks. Furthermore, the paper discusses the challenges and advantages over the convention modulation schemes.

Performance Enhancement of Telemedicine Network by Free Space Optics Links Provisioning

“…To achieve higher data rates, WDM based FSO systems are being deployed [17]. In this work, for the telemedicine network, WDM based FSO system with a data rate of 1.25 Gbps is considered [18]. Figure 1 shows a detailed block diagram of telemedicine network model utilizing RF and FSO at the specialized hospital premises, which has been built on WMN.…”
