The aquatic research community is rapidly equipping ecological sites with a broad range of sensors and instruments. However, the development of aquatic sensing networks is significantly lagging terrestrial counterparts. It is widely recognized that an aquatic counterpart to low cost, low power, wireless radios is needed to advance the state-of-the-art in underwater sensor networks. Unfortunately, there are few open-architecture, low power and low cost underwater acoustic modems. This project looks at an alternative hardware platform for wireless underwater communication. Reconfigurable devices will be used to create a software defined acoustic modem (SDAM) ? the underwater counterpart to software defined radios being proposed for future generations of terrestrial communications. The SDAM can be remotely programmed, which enables adaptive sensing capabilities and changes to the network without physically retrieving the device. Since the communication protocol is programmed into the modem, the same SDAM board can be used for a variety of different underwater environments. The ultimate goal is to develop a prototype SDAM that uses a reconfigurable device for physical layer processing. This requires careful design of a system architecture that can communicate with the sensors, interface with acoustic transducer(s), efficiently compute physical layer algorithms, and provide services to the rest of the network stack. The broader impacts of this project center around the incorporation of embedded and reconfigurable computing systems into course material, and the use of the SDAM for ecological research, which enables long-term understanding of many ecological processes, including the effects of environmental degradation and climate change on coastal and lake ecosystems.

水生研究界正在迅速为生态场所提供广泛的传感器和仪器。 但是，水生感应网络的发展显着落后于陆地。 人们普遍认识到，需要与低成本，低功率，无线收音机的水生，以促进水下传感器网络中的最新时间。 不幸的是，几乎没有开放式结构，低功率和低成本的水下声学调制解调器。 该项目着眼于无线水下通信的替代硬件平台。 可重构设备将用于创建软件定义的声学调制解调器（SDAM）？水下与软件定义的无线电相对，为子孙后代的地面通信提出。 可以将SDAM远程编程，从而在不实际检索设备的情况下对网络进行自适应感测功能和更改。 由于通信协议被编程到调制解调器中，因此可以将同一SDAM板用于各种不同的水下环境。 最终目标是开发一个使用可重构设备进行物理层处理的原型SDAM。 这需要仔细设计可以与传感器通信的系统体系结构，与声音传感器进行交流，有效地计算物理层算法，并为其他网络堆栈提供服务。 该项目中心围绕将嵌入式和可重构计算系统纳入课程材料的更广泛影响，以及将SDAM用于生态研究，这可以长期对许多生态过程的了解，包括环境退化和气候变化对沿海和湖泊生态系统的影响。
