Paper Abstract

In this paper we describe a free-space optics (FSO) based mobile sensor network that is not subject to RF interference common to wireless sensor networks. FSO-based mobile sensor networks can potentially be used in applications where security of communication, including freedom from susceptibility to jamming, is important. The design of nodes containing multiple transceivers each composed of an LED and an angle-diversity array of identical photo detectors is discussed in this paper. Depending on the number of photodetectors in the array and the angular field of view of each photo detector we may obtain an increase in the signal to noise ratio of the overall optical communication system.
