- 通信网络的节点部署优劣直接关系到舰船通信能力，针对舰船通信网络资源利用能力低的问题，提出能量受限约束下舰船通信网络节点动态协同部署方法。分析能量受限的节点动态特性，得出能量约束条件下通信网络系统节点的闭环特性。计算舰船通信网络节点网格密度，利用K-均值聚类以及粒子群2种算法找寻出最优节点位置，实现舰船通信网络节点动态协同部署。实验结果表明，本文方法的通信传输能耗小，信息吞吐量高，网络生命周期长。
The node deployment of communication network is directly related to the ship's communication capability. Aiming at the problem of low utilization of ship communication network resources, a dynamic cooperative deployment method of ship communication network nodes under energy constraints is proposed. Build a channel model to define the network information transmission capacity, analyze the dynamic characteristics of nodes with energy constraints, and obtain the closed-loop characteristics of nodes in the communication network system under energy constraints. Calculate the node grid density of the ship communication network, integrate the channel model, node dynamic characteristics and node grid density, and use K-means clustering and particle swarm optimization to find the optimal node location to achieve the dynamic collaborative deployment of ship communication network nodes. Experimental results show that the proposed method has low communication transmission energy consumption, high information throughput and long network life cycle.
