为了提高船舶移动网络的全网能量均衡性,提出一种基于能量均衡控制的船舶移动网络中节点跨域访问方法。建立船舶移动网络移动节点的分布部署模型,采用最短路径寻优方法进行节点的路径规划,结合通信负载均衡性进行船舶网络传输信道均衡设计,对船舶移动网络中各簇首节点采用链路增益控制方法进行传输路由设计,计算移动船舶网络的全网能量负载开销,采用能量均衡控制方法实现船舶移动网络节点的跨区域访问。仿真结果表明,采用该方法进行船舶移动网络中节点跨域访问,提高了节点的正确传递概率,船舶移动网络的全网信道均衡性较好,改善了网络的数据传输和通信性能。

In order to improve the energy balance of ship mobile network,a cross-domain access method based on energy equalization control is proposed,and the distributed deployment model of mobile nodes in ship mobile network is established.The shortest path optimization method is used to plan the path of the nodes,the ship network transmission channel balance is designed by combining the communication load balance,and the link gain control method is used to design the transmission route for each cluster head node in the ship mobile network.The energy load overhead of the whole network is calculated,and the energy balance control method is used to realize the cross-area access of the nodes in the ship mobile network.The simulation results show that the method is used to access the nodes across the domain in the ship mobile network.The correct transmission probability of nodes is improved,the channel equalization of ship mobile network is better,and the data transmission and communication performance of the network is improved.
