水下航行器被用于各种应用，包括水下数据收集任务。绳索连接限制了任务的行驶距离和可在同一区域行驶的车辆数量，而在车辆上添加声学通信则为它们提供了几项功能。然而，由于水声信道的低带宽-这导致低数据速率-以及由水声调制解调器的信道传播延迟和处理延迟两者造成的时间开销，需要有效的协议。本文提出了一种隐式数据压缩和传输协议，用于环境监测任务，如水中物理化学参数的自适应采样。在车辆和控制中心之间的半自主方式中，除非发现环境数据和/或运动学数据不可预测，否则双方在数据传输中保持沉默，只要它们可以估计和预测对方的动作。我们的设计将人类置于发送高级控制命令的循环中。实验是使用带有WHOI微型调制解调器的自动驾驶汽车在新泽西州的拉里坦河、萨默塞特、普林斯顿的卡内基湖和红岸的海洋公园进行的。
Underwater vehicles are utilized in various applications including underwater data-collection missions. The tethered connection constrains the mission both in distance traveled and number of vehicles that can run in the same area, while the addition of acoustic communications onto the vehicles grants them several functionalities. However, due to the low bandwidth of the underwater acoustic channel---which leads to low data rates---and the time overhead imposed by both the channel propagation delay and the processing delay by the acoustic modems, efficient protocols are required. In this paper, an implicit data-compression and transmission protocol is proposed to carry out environmental monitoring missions such as adaptive sampling of physical and chemical parameters in the water. In a semi-autonomous manner between the vehicle and the control center, both sides keep silent in data transmission as long as they can estimate and predict the actions of the other side, unless environmental data and/or kinematic data are found to be unpredictable. Our design puts the human in the loop to send high-level control commands. Experiments were conducted using an autonomous vehicle with WHOI micro-modems in the Raritan River, Somerset, Carnegie Lake in Princeton, and in the Marine Park in Red Bank, all in New Jersey.
