面向水下AUV辅助数据收集的动态窗口调度与协作预约MAC协议
Dynamic window scheduling and collaborative reservation MAC protocol for AUV-assisted underwater data collection
摘要
Abstract
Autonomous underwater vehicle(AUV)-assisted networks were prone to access collisions and link interrup-tions under high loads,which seriously affected data collection efficiency.To maximize data collection efficiency and channel utilization,a MAC protocol based on dynamic window scheduling and collaborative reservation,named DWS-CR-MAC,was proposed.Firstly,an adaptive contention window mechanism based on a collision model was designed,and the optimal window was dynamically adjusted to mitigate access collisions without prior topology information.Sec-ondly,a dynamic scheduling and pruning strategy based on remaining link lifetime(RLL)was proposed,and unstable links were eliminated using the AUV mobility model.Finally,a cooperative recovery mechanism based on neighbor overhearing was constructed,and supplementary access for collided nodes without random contention was achieved by piggybacking requests.Simulation results show that the proposed protocol effectively mitigates access collisions and link interruptions under high loads,improves average network throughput and packet delivery ratio,and reduces control over-head ratio and average energy consumption.关键词
