Acoustic communication characteristics in UWDBCSN

An underwater ad-hoc sensor network differs from terrestrial network in terms of energy consumption, communication and topology. An acoustic communication is identified as energy efficient way of communication in such networks. Further a multi-hop acoustic communication from bottom of the water to the surface adds many folds to save sensors' energy. To avoid battery recharging or replacement a better topology and improved communication method needs to be developed. In order to exploit multi-hoping advantages and to save energy we have proposed earlier an Under Water Node-Density Based Clustering Sensor Network Protocol (UWDBCSN). In this paper we will give a glimpse of that protocol and discuss some consequences of Acoustic Communication like spreading loss, absorption loss and path loss in the protocol.
