Cross-Domain Communication Buoy System Based on Optimal Communication Link Selection

Abstract

The existing marine buoy communication mode is single, with low reliability, high packet loss rate, and poor real-time performance, which cannot meet the needs of large-scale marine data acquisition and cross-domain communication. In order to further strengthen the construction of marine global interconnection, a cross-domain communication buoy system with multi-source communication as the core was designed and manufactured. The system could complete the switching of multiple communication modes, multi-source information acquisition, and multi-link real-time cross-domain communication. An optimal communication link selection algorithm was designed for the system. According to the real-time signal quality of each communication module, the optimal communication link was selected to improve the reliability of communication. At the same time, the communication module with poor signal quality was closed to reduce the problem of large redundancy and power consumption of system communication that may occur when multiple communication methods are used at the same time. The experimental results show that the system realizes the cross-domain transmission of water surface and underwater data, and the multi-source communication design is feasible. The communication links are stable and reliable, and the comprehensive communication success rate is more than 99%. It provides a reference for the construction of a marine global observation network and communication network.
