摘要
普通船舶传输节点选择算法,存在数据传输效率较低、通信节点覆盖面积有限等弊端。为解决上述问题,设计基于船舶无线通信网络的Co MP传输节点选择优化算法。通过网络信道编码、通信链路层协议选择2个步骤,完成船舶无线通信网络环境的搭建。通过Co MP传输节点选择、节点数据预编码、优化判决门限计算3个步骤,完成优化后传输节点选择算法的搭建。模拟算法运行环境,设计对比实验结果表明,优化后算法与普通算法相比,有效解决数据传输效率低下、通信节点覆盖面积有限等问题,为船舶通信数据的稳定传输提供可能。
The selection algorithm of common ship's transmission node has the disadvantages of low data transmission efficiency and limited coverage area of communication nodes. To solve the above problems, we design an optimization algorithm of Co MP transmission node selection based on ship wireless communication network. Through the two steps of network channel coding and communication link layer protocol selection, we complete the construction of ship wireless communication network environment. Through three steps of Co MP transmission node selection, node data precoding and optimization decision threshold calculation, we finish the optimization of transmission node selection algorithm. The experimental results show that the optimized algorithm can effectively solve the problems of low efficiency of data transmission and limited coverage area of communication nodes, which can provide a stable transmission for ship communication data.
