Investigation of underwater sensor networks localization and analysis the performance

Abstract: Underwater wireless communication opens up a wide field of application in the field of civilian and military surveillance and exploration of the oceans. Sensor networks, consisting of sensor nodes exposed under and above water, use ultra- and infrared for communication in order to transmit data in the water. This thesis gives an overview of the problems associated with the acoustic communication under water and presents appropriate solutions. It also examines the current modulation methods and provides an overview of current applications. In this thesis, the system related to the underwater communication system is defined, information about the parameters affecting the communication is given and the theoretical analyzes such as the behavior of the underwater environment is presented. The simulation work is performed for these parameters in the simulation environment. The most recent studies is evaluated and comments and analyzes is presented.
