uw-WiFi: An Underwater Wireless Sensor Network for Data Collection and Network Control in Real Environments

Authors: Jifeng Zhu, Xiaohe Pan, Jun-Hong Cui, Tingting Yang

In this paper, we propose an UAN with the WiFi network architecture called uw-WiFi, with the goal of realizing a hydroacoustic network that can be stably applied in the real environments. We conduct a case experiment with 5 different kinds of network nodes. The test results show that the uw-WiFi network is able to meet the current urgent application needs, and to achieve a satisfying network performance.

A Variational Auto-Encoder Model for Underwater Acoustic Channels

Authors: Li Wei, Zhaohui Wang

An underwater acoustic (UWA) channel model with high validity and re-usability is widely demanded. In this paper, we propose a variational auto-encoder (VAE)-based deep generative model which learns an abstract representation of the UWA channel impulse responses (CIRs) and can generate CIR samples with similar features. A customized training process is proposed to avoid the model collapse and being trapped in a gradient pit. The proposed deep generative model is validated using field experimental data sets.
