A Scheme for managing the presence of Ambient Lights in Diffuse Infrared Wireless Home/Office Network

摘要

In recent years, optical wireless communications has emerged as a suitable alternative to radio frequency transmission for short-range indoor data communications since infrared offers several advantages over radio. To utilize the advantages of diffuse IR wireless system such as very high data rate and security over the RF system in an indoor environment we need to exploit the ubiquitous computing and smart sensing mechanism which could be used to mitigate some of the drawbacks of diffuse IR such as different background light strengths at different places, in which case at some places BER gets deteriorated or receiver fails to detect the signal due to its limited sensitivity. In this paper a scheme for tackling the ambient or background lights of different strengths in different locations in a typical indoor space using smart and aware environment has been discussed.
