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.

水下声学传感器网络（UWSN）是一种新兴的网络平台，具有广泛的潜在应用，从环境监测、工业仪表监测和控制到军事监视和安全监测。最近人们对 AUV（自主无人驾驶车辆）设计和部署的兴趣和工程活动不断增加，进一步推动了 UWSN 研究的进展，这要求 UWSN 具有移动特性。 AUV（或AUV组）的使用将有利于网络部署策略，最大化网络覆盖，并实现高速组网；然而，由于部署稀疏、通信带宽低、传播时延和时延变化大、频率依赖衰减、强多径等特点，也给定位和同步、路由规划、介质访问控制、协调估计和网络连接等方面带来了新的挑战。和多普勒效应，以及 UWSN 声波信号的长距离。
