摘　　要：针对水下无线传感器网络节点更换困难、能量有限的特点,提出了一种基于改进正余弦算法的节能路由。在簇的形成过程中,利用改进的正弦余弦优化算法来选举簇头,综合能量、节点密度、通信距离三方面因素并讨论相应权重,为簇头选择设计了更加合理的适应度函数。簇内单跳传输,簇间传输时则采用多跳传输,通过限制深度、能量及转发区域选择合适的下一跳,将采集的信息传递给水面。经网络仿真验证,在相同条件下,该算法较传统LEACH算法和KACO、DUCISCA算法,将正常工作时间延长了69.10%、24.78%、14.94%,能够有效均衡网络能耗,延长网络寿命,提高数据传输率。Aiming at the difficulty of node replacement and limited energy of underwater wireless sensor network,the paper proposes an energy-efficient routing protocol based on improved sine cosine algorithm.In the process of cluster formation,it uses the improved sine cosine optimization algorithm to select the cluster head,considering the three factors of energy,node density and communication distance,and discusses the corresponding weights,then designs a more reasonable fitness function for cluster head selection.Single-hop transmission within the cluster,between the clusters used multi-hop transmission.The algorithm transmits the collected information to water surface by limiting the depth,energy and forwarding area to select the appropriate next hop.The network simulation results show that under same conditions,the work hours increases by 69.10%,24.78%and 14.94%compared with the traditional LEACH algorithm,the KACO and DUCISCA algorithm,which can effectively balance network energy consumption,prolong network life,and improve data transmission rate.
