Evaluating the Impact of Node Density and Area Shape in Underwater Wireless Sensor Networks

Most of Underwater Wireless Sensor Networks (UWSN) applications are tolerant to delays and unstable links in the underwater environment, where acoustic waves are used instead of electromagnetic radio waves. Commercial UWSN applications will primarily focus on limited areas of the sea or in small pools, lakes or ponds for specific purposes. Node scarcity and movement patterns create different environment for data collection in underwater communication. In this paper, we investigate the impact of the area shape and node density in UWSN, by comparing different routing protocols by simulations. From simulation results we can conclude that node density and area shape affect the performance of both epidemic and FBR.
