Modelling and simulation of underwater low-power wake-up systems

Abstract

Underwater Wireless Sensor Networks (UWSN) have become an important area of research due to its many possible applications. One example are the long-term monitoring applications were the nodes only need to be awake during a small fraction of time. This kind of applications can greatly benefit from low-power, wake-up systems. However, despite the fact that the simulations can greatly improve the development time of new algorithms and features, optimizing their performance, up until today there is no wake-up system model available. In this paper a low-power underwater wake-up model for the ns-3 simulator is going to be presented. Using this model the, as far as we know, only two available underwater modems with integrated wake-up capabilities are compared in terms of energy consumption. © 2012 ICST Institute for Computer Science, Social Informatics and Telecommunications Engineering.
