海洋跨介质通信自组网络设计与实现

Design and Implementation of a Cross-Media Ad Hoc Network for Maritime Communication

世界各国在海洋资源开发、环境监测、搜索救援、协同巡查等领域的活动日益增频繁,加剧了对海洋跨介质通信的需求。设计了一种基于海上浮标的海洋分布式跨介质通信网络,融合水声、无线电、卫星通信等多种通信手段于一体,通过无线电自组网实现局部立体海域的通信覆盖,为水下用户提供互联互通以及与陆网联通的通用接口。重点研究了跨介质通信网络体系,设计了面向海洋复杂环境的网络通信协议及路由算法,并搭建原型网络,开展网络覆盖范围、吞吐率等关键指标的海试验证。经测试,该网络能够实现局部立体海域的准实时通信,由3节点组成的跨介质通信网络能够提供3kbps半径6.6km的吞吐量及海面覆盖范围。

With increasing activities in marine resource exploration,environmental monitoring,search and rescue,and coordinated patrols,the demand for cross-media communication in maritime environments intensifies.This paper presents the design of a distributed cross-media communication network based on ocean buoys,integrating acoustic,radio,and satellite communication methods to achieve communication coverage across localized 3D maritime areas through a radio-based ad hoc network.This network provides an interoperable interface for underwater users to connect with each other and with terrestrial networks.The study focuses on the architecture of cross-media communication networks,designing network protocols and routing algorithms tailored to complex marine environments.A prototype network is constructed to conduct sea trials,verifying key metrics such as coverage range and throughput.Test results show that the network enables quasireal-time communication within localized maritime areas,with a cross-media network of three nodes achieving a throughput of 3kbps over a 6.6km radius of surface coverage.
