Intelligent AUV-Assisted Heterogeneous Underwater Acoustic Sensor Networks

水声传感器网络(UWSN)是一种新兴的网络平台，具有广泛的潜在应用前景，从环境监测、工业仪表监测和控制到军事监视和安全监测。近年来，人们对自主无人驾驶飞行器(AUV)的设计和部署越来越感兴趣和工程活动，这进一步推动了UWSN研究的进步，这就要求UWSN具有移动性。AUV(或AUV组)的使用将促进网络部署策略，最大化网络覆盖，并实现高速联网；但由于UWSN的稀疏部署、低通信带宽、大传播延迟和延迟波动、频率相关衰减、强多径和多普勒效应以及远距离传播，这也给定位与同步、路径规划、介质访问控制、协调估计和网络连通性提出了新的挑战。

The UnderWater acoustic Sensor Network (UWSN) is an emerging networking platform that promises a wide range of potential applications, ranging from environmental monitoring, industrial instrumentation monitoring and control, to military surveillance and security monitoring. The advancement of UWSN study is further augmented by the recent increasing interest and engineering activity in the design and deployment of AUVs (Autonomous Unmanned Vehicles), which has required that UWSNs incorporate mobility properties. The use of AUV (or groups of AUVs) will facilitate network deployment strategy, maximize network coverage, and enable high-speed networking; however, it also raises new challenges for localization and synchronization, route planning, medium access control, coordinated estimation, and network connectivity due to the sparse deployment, low communication bandwidth, large propagation delay and delay variation, frequency dependent attenuation, strong multi-path and Doppler effects, and long reach of the acoustic signals of the UWSNs.
