Wireless ultraviolet network models and performance in noncoplanar geometry

Atmospheric scattering for ultraviolet signals enables non-line-of-sight communication of a transmitter-receiver pair on-the-move and adaptive network configuration. In this work, we first develop an experimentally validated path loss model which characterizes both multiple scattering and arbitrary pointing with noncoplanar geometry. Then we discuss how to achieve full duplexing. We suggest transmission throughput as a metric to evaluate the performance of a wireless network consisting of randomly distributed nodes operating in such a channel. We further study the effects of some key network parameters including node spatial density, transmission probability and signal detection threshold via the lower bound of the transmission throughput. Performance optimization in the parameter space is performed numerically and simulation results are demonstrated.
