名称：Characteristics of Radio Wave Propagation in Ship Cabin
讲座简介：The main engine room is the power center of a ship and monitoring the statusof key equipment in the room during navigation is important to the stability and safety of the ship's operation. Wireless sensor networkshave been implemented in such applications and radio signal propagation has to be investigated to ensure that collected information will be transmitted to the local gateway (base station). This presentationwill report some recent resultsofradio signalpropagation inside a ship cabin for wireless communication by using the ray-tracing method.With the simulation tool, a three-dimensional model of radio wave propagation in typical hull ship cabin with the main diesel engine and control room is established. The parameters of multipath propagation prediction and received power along the selected pathsare calculated. Besides, through comparative analysis with experimental test, the main influence of objects in the cabin on the characteristics of wireless signal is given. The results clearly demonstrate that the wireless network is promising and quite feasible and the predictions give relatively good agreement with experimental data. The investigation could provide guidance for the design of wireless communication network in terms of signal coverage and base station locations.
