A comparison between underwater global data gathering with actual measurement for simulation of underwater channel

摘要

This paper focused on underwater physical and environmental data collection such as temperature, salinity, depth, surface agitation and seabed topography based on online global databases. These data are essential due to more realistic simulation of underwater communication channel. Physical data values are different based on locations and weather patterns. A network designer has to collect by measurements for several times. The measuring procedure is often very cumbersome, time consuming and expensive. Moreover, critical problem arises when the data is not general and the data may change for next year as well. This research introduces a method for collecting underwater physical data based on weather satellites, geology software and global online resources such as NOAA. This study evaluates difference between measured data with the collected data from online databases. The result indicates that the collected salinity data from proposed method is acceptable with 0.3 Psu tolerance and is 0.5 °C for temperature.
