Multi-access Protocols for Directional Ultraviolet Communication with Node Tracking

Due to its multiple advantages, ultraviolet (UV) communication exhibits significant potential for outdoor mobile communication. This paper proposes novel multi-access protocols for UV mobile communication networks, where each secondary node employs a single directional UV transceiver and tracks the primary node. The proposed protocols are evaluated through simulations based on a network model that accounts for node movement, node tracking, and UV link gain. Simulation results demonstrate that the proposed protocols outperform the conventional Carrier Sense Multiple Access protocol.
