AOSN MURI: Utility Acoustic Modem and Robust Communications
1998
Johnson, Mark
To create and demonstrate a reactive survey system, capable of long-term unattended deployments in harsh environments. We refer to such a system as an Autonomous Ocean Sampling Network (AOSN). The goal of the Utility Acoustic Modem effort is to develop a low-power hardware platform and a robust signaling strategy for data communications between components such as robotic vehicles, moorings, or ocean-bottom assets, in an AOSN. To develop and evaluate a complete hardware and software solution for acoustic communications between vehicles and moorings in an AOSN system. Emphasis is on the reliability of the communications link in the face of vehicle self-noise, other active systems (e.g., navigation), and rapidly changing multi-path. To this end, we are developing a suite of signaling techniques, covering a wide range of data-rates and coding strategies, together with a means for selecting the optimal method on a packet-by-packet basis. This will lead to a responsive system, capable of high data-rate in good channels and some data transfer even in very poor channels.
