Abstract:
1. A method for providing communications in an unattended ground sensor network, for use in both line-of-sight (LOS) and non-line-of-sight (NLOS) conditions, the method comprising the steps of: transmitting and receiving ultraviolet radiation having a wavelength within the solar blind region, wherein the ultraviolet radiation is transmitted and received from a plurality of unattended ground sensing nodes, and wherein the plurality of unattended ground sensing nodes are arranged both in a LOS network, which communicates via LOS communication, and in a NLOS network, which communicates via NLOS communication; transmitting the ultraviolet radiation from the plurality of unattended ground sensing nodes to a gateway node; and transmitting the ultraviolet radiation from the gateway node to a remote receiver via LOS communication.
