摘　　要：路由优化是提升水声通信网络性能的重要手段,但目前路由优化效果并不理想,在实践中不仅网络链路利用率比较高,而且包投递成功率比较低,针对当前水声通信网络路由优化存在的问题,提出基于改进粒子群算法的水声通信网络路由优化方法。以链路带宽利用率最大、链路时延最小为目标建立网络路由多目标优化函数,并设定时延、带宽、包投递率、时延抖动以及成本约束条件,对粒子群算法改进并利用改进算法对符合约束条件的目标函数最优解求解,得到最优路由策略,实现基于改进粒子群算法的水声通信网络路由优化。经实验证明,在设计方法应用下网络链路利用率得到了明显的降低,包投递成功率也得到了明显的提升,具有良好的网络路由优化效果。routing optimization is an important means to improve the performance of underwater acoustic communication nctwork,but the routing optimization effect is not ideal,in practice not only the network link utilization rate is high,and the delivery success rate is low,in view of the current underwater acoustic communication nctwork routing optimization problems,based on improved particle swarm algorithm of underwater acoustic communication network routing optimization method.With the link bandwidth utilization maximum,link delay minimum goal to establish network routing multi-objective optimization function,and set the delay,bandwidth,package delivery rate,delay jitter and cost constraints,the particle swarm algorithm to improve and use the optimal solution,the optimal routing strategy and realize the underwater acoustic communication network routing optimization based on improved particle swarm algorithm.It is proved that under the application of the design method,the utilization rate of the network link has been significantly reduced,and the success rate of the package delivery has also been significantly improved,which has a good optimization effect of the network routing.
