摘要
水声传感器网络(Underwater Acoustic Wireless Sensor Networks,UWSNs)由于复杂的水下环境,面临着投递率低、传播延迟高和节点能耗大等挑战.为解决这些问题,文章提出了一种自适应锥体矢量路由协议(Adaptive Cone Vector Routing Protocol,ACVRP),根据节点密度自适应调整锥体区域大小和方向,减少冗余通信和网络能耗,并根据节点的剩余能量和节点在锥体区域中的位置确定节点转发优先级,以提高投递率、减少传输跳数.仿真实验结果显示,与VBF、AHH-VBF和AHHC-VBF相比,ACVRP在包投递率、能效和端到端延迟方面均表现更佳.
Abstract
Underwater Acoustic Wireless Sensor Networks(UWSNs)encounter challenges such as low delivery rates,high propagation delays,and high node energy consumption due to the complex underwater environment.To address these issues,this paper proposes an Adaptive Cone Vector Routing Protocol(ACVRP).The ACVRP adaptively adjusts the size and direction of the cone region based on the node density to reduce redundant communication and network energy consumption.The forwarding priority of the node is determined based on its residual energy and position in the cone region to improve delivery rate and reduce transmission hops.Simulation results demonstrate that ACVRP outperforms VBF,AHH-VBF,and AHHC-VBF in terms of packet delivery rate,energy efficiency,and end-to-end delay.
