近海海洋环境对水声网络性能影响试验评估
Experimental Evaluation of Influence of Offshore Marine Environment on Underwater Acoustic Network Performance
摘要
Abstract
Underwater acoustic network has become the key technology of ocean information acquisition,transmission and perception,and has been widely studied.At present,the research of underwater acoustic communication mainly focuses on the factors affecting underwater acoustic channels such as delay and multipath.When marine environment changes,the characteristics of delay and multipath in underwater acoustic channel will change accordingly,which will affect the performance of underwater acoustic communication system.However,study on the direct correlation between complex marine environmental phenomena and underwater acoustic network performance is still limited.Based on the underwater acoustic network experiment conducted in Xiamen sea area,the impact of typical offshore marine environmental factors such as winds,waves and tides on the underwater acoustic network performance are evaluated from the average end-to-end delay,packet loss rate and other network performance indicators.Based on the test results,the correlation between the marine environment and the underwater acoustic network performance is analyzed.The experimental results show that the delay of underwater acoustic communication network is affected by temperature,wind speed and tide level.The evaluation and analysis results of this paper can provide reference for the design and application of underwater acoustic communication network in complex offshore marine environment.关键词
