An Underwater Wireless Sensor Network with Realistic Radio Frequency Path Loss Model

International Journal of Distributed Sensor Networks, 2013
We propose an Underwater Wireless Sensor Network (UWSN) for near-shore applications using electromagnetic waves (EM). We also introduce a realistic path loss model for estimating the attenuation encountered by EM waves in underwater environments.
