Communication Architecture for Underwater Wireless Sensor Network

Abstract

Investigations in hydrologic sciences are bounded because most of existing water surveillance methods are manual.Such systems are incapable to gather information at spatial and temporal level due to location constraints.In this paper, we present a new communication architecture for Underwater Wireless Sensor Network (UWSN) based on acoustic communication.However, unique challenges offered by underwater environment are main hindrance in deployment of UWSN in real life applications.So, we discuss various communication methodologies to figure out which one suits best to the requirements of UWSN.Our simulation results illustrate change in data transmission rate, energy consumption and transmission time w.r.t transmission range and number of nodes in network.Results prove that multi-hop communication offer high transmission rate, large bandwidth.Moreover, multi-hop communication is much more energy and time efficient than direct communication.
