Wireless sensor network for underwater communication

IET Conference on Wireless Sensor Systems (WSS 2012), 2012
Although, attenuation in Electromagnetic (EM) wave propagation underwater is high at high frequencies, the theory predicts that propagation is possible at some useful distance in the lower Industrial, Scientific and Medical (ISM) band. The aim of this paper is to study the feasibility of using radio transceivers underwater for developing a Wireless ...
