Abstract
The deployment of wireless sensor network in ship application traditionally relies on human experience and lack of theoretical analysis so far. Based on electromagnetic theory calculation (ray-tracing method) and experimental measurement, this paper investigates the propagation of radio signals inside ship cabin for wireless sensor network with LoRa (Long Range) technology. A three-dimensional model of radio wave propagation in typical hull ship cabin with the main diesel engine and central control room is established. The multi-path propagation prediction is carried on and the received power of the receiver is calculated. Besides, through comparative analysis with experimental test, the main influence of cabin spatial factors on the characteristics of wireless signal is discussed. The results clearly demonstrate that the wireless network with LoRa band is possible and quite feasible in ship cabin, and the simulated results could give well agreement with experimental data about the rules of influence on wireless signal in different areas of the ship's cabin. Some important guidance is also given for communication link design of actual LoRa network in ship.
