A Robust Multihop Underwater Network for Sensing Applications - Implementation and Experimental Evaluation

Free registration required

Executive Summary

Various novel applications of underwater acoustic sensor networks have emerged or been proposed in recent years. In this paper, the authors present a complete system implementation of a robust multi-hop underwater network for sensing applications. At the core of the system is a robust data delivery scheme which uses opportunistic Automatic Repeat reQuest (ARQ) with bidirectional overhearing. They demonstrate the modular and hardware-independent nature of their implementation by porting and deploying the software architecture and underwater network stack into hydroacoustic modems from different vendors.
