摘　　要：针对水下自组织网络路由协议中,AUV选择下一跳时存在传输不可靠、网络整体性能差的问题,通过借鉴机会网络的路由转发思想,改进下一跳AUV评估度量,提出一种基于AUV综合评估的机会路由协议。首先采用动态调整移动性评估模型与转发能力评估模型所占权重的方法对AUV进行综合评估,然后利用转发结果的反馈值更新评估路由表,最后在累计多次转发反馈值后,逐渐实现数据包的精准投递。实验结果表明,与现有多种路由算法相比,CAOR协议在复杂多变的水下环境具有提高数据包投递率、减少平均端到端时延、降低转发过程能量消耗的优点,CAOR协议的可靠性和节能两个指标在水下自组织网络通信应用中均大幅提升。In order to solve the problems of unreliable transmission and poor overall network performance when the AUV selects the next hop in the routing protocol of the underwater self-organizing network,the next-hop AUV evaluation metric is improved through the routing and forwarding idea of the opportunistic network,and an opportunistic routing protocol based on AUV comprehensive evaluation is proposed.First,the method of dynamically adjusting the weight of the mobility evaluation model and the forwarding capability evaluation model was used to comprehensively evaluate the AUV.Then,the feedback routing table was updated with the feedback value of the evaluation result.Finally,after accumulating multiple forwarding feedback values,the accurate delivery of data packets was gradually realized.The experimental results show that compared with the existing routing algorithms,the CAOR protocol has the advantages of improving the packet delivery rate and reducing the average end-to-end delay in the complex and changeable underwater environment,which effectively improves the overall network performance.
