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.

水下声传感器网络（Underwater acoustic Sensor Network，UWSN）是一种新兴的网络平台，具有广泛的应用前景，从环境监测、工业仪表监控到军事监视和安全监控。UWSN研究的进展进一步增强了最近越来越多的兴趣和工程活动在AUV（自主无人驾驶车辆）的设计和部署，这要求UWSN纳入移动性属性。AUV的使用（或AUV组）将促进网络部署策略，最大限度地扩大网络覆盖范围，并实现高速联网;然而，由于稀疏部署、低通信带宽、大的传播延迟和延迟变化，频率相关衰减，多径效应和多普勒效应强，水声信号到达距离长。
