In order to decrease the energy consumption of wireless sensor network nodes, ultraviolet was utilized as the signal carrier of wireless sensor network. Firstly, the energy consumption of single hop and multiple hops were studied based on the energy model of UV light sensor nodes, then the mathematical expression for calculating optimum hops was obtained. The average energy consumption of single hop communication, multiple-hop communication and optimum communication were simulated, and the simulation results were consistent with theoretical analysis. Mobile sink node can resolve the uneven energy consumption problem resulting from multiple hop communication. The influence of network average energy consumption, loss packet ratio, and delay under different mobile velocity of sink node was simulated and analyzed. The simulation results indicate that the different mobile velocity of sink node have different influence on the network' performance, and that mobile sink node can decrease network average energy consumption by selecting suitable mobile velocity according to different scenes.
