Considering strong signal attenuation of the large-angle non-line-of-sight (NLOS) link achieved due to ultraviolet (UV) scattering properties, we propose increase UV communication gain under a large angle via generating agglomerate fog within certain range as secondary light source. In this study, channel model with locally scatterers from is proposed based on Monte Carlo ray-tracing approaches. Mie theory adopted calculate atmospheric parameters, further evaluate non-uniform atmosphere. The...
To efficiently exploit the space division multiplexing of ultraviolet (UV) communication, we apply link coverage characteristics to construct a conflict graph and design conflict-free protocols for two-layer UV communication network. The network is divided into two layers: first-layer forms backbone second-layer serves as local access. We routing model medium-access control (MAC) model. Then propose Routing-MAC joint scheduling based on graph. investigate system throughput delay under...
To adapt to different transmission power and distances, we design a rate-compatible protocol realize rates for ultraviolet (UV) communication. We have designed ensembles based on low-density parity-check (LDPC) codes, incorporating various code lengths working under channel conditions. Furthermore, the direct sequence spreading technique is adopted obtain codes in weaker Through simulating frame error rate (FER) performance across signal background radiation intensities, table of switching...
