| The ocean is rich in marine resources,and its prudent usage is good for our economic prosperity.At the same time,our country is one of the most severely impacted countries in the world by marine disasters,which result in significant economic losses.We need to monitor marine environmental indicators in realtime to respond to marine disasters quickly and minimize economic damages.As a result,establishing an effective marine monitoring network is critical.Based on a comprehensive analysis of the maritime wireless ad hoc network,we assess the problems and obstacles encountered at each level of the architecture.The antenna polarization mismatch between transceiver nodes is one of the key reasons for the unstable link quality of the surface nodes due to the oscillation of the antennas on the buoy nodes produced by the wave motion,according to an indepth analysis of the antenna principle.To solve this problem,this work provides a link quality model and quality evaluation method for floating nodes,as well as a link stability-based opportunity routing protocol.The simulation verification mechanism is also in place.The following is the main focus of this paper.1.This study offers a model and quality assessment approach for sea surface node swing and link quality stability to solve the problem of floating sea surface nodes impacting link quality stability.The antenna’s attitude information is calculated using the inertial measurement unit of the sea surface buoy node,which is utilized to determine the node link’s stability.2.This study proposes an effective routing algorithm for sea surface data transfer under connection instability to improve the efficiency of the data transmission.The protocol employs the opportunistic forwarding method,which can simultaneously try numerous lossy links to enhance network forwarding success rates.This routing algorithm creates a new routing metric based on the node jitter model and the link stability metric to assist the source node in selecting the node with the highest link stability from the forwarding set.The routing protocol’s performance is compared to that of the existing self-organizing network routing protocols AODV and DSDV in a simulation platform.In terms of delay,packet loss rate,and energy consumption in the ocean environment,simulation findings show that the opportunistic routing of the ocean-oriented wireless selforganizing network suggested in this research outperforms existing wireless selforganizing network protocols.3.This study builds and implements an opportunity routing system for the marine self-organizing network to suit the data gathering,forwarding,storage,and monitoring needs of maritime monitoring networks.The system is made up of a data collection module,a forwarding,and storage module,and a query module that can offer users high-quality marine environment monitoring data so they may monitor the environment in real-time and efficiently. |
