Adaptive cone vector routing protocol for underwater wireless sensor networks
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.
