Data communication Issues in Underwater Sensor Network

Abstract

The Underwater medium is extremely demanding and uncalculable caused by number of issues, for example limited bandwidth, node mobility, battery power limited, more severe noise, and interference, shadow zones, movements of the sensor nodes with high water currents, high error rate, Attenuation, Absorption, Corrosion and fouling and long and varying propagation delay. In this paper taken many protocols which is solve node mobility issues and also define which one is more efficient compare to others one. Node mobility is a major problem that created cause of mobile nature of nodes. Due to environmental conditions the source and the destination nodes displaces from their original positions during communication, A communication failure is occure in this situation.
