Directional Vector Forward Focused Beam Routing Protocol for Underwater Sensor Network

Abstract

Providing scalable and efficient routing services in underwater sensor networks (UWSNs) is very challenging due to the unique characteristics of UWSNs. Firstly, UWSNs often employ acoustic channels for communications because radio signals do not work well in water. Compared with radio-frequency channels, acoustic channels feature much lower bandwidths and several orders of magnitudes longer propagation delays. Secondly, UWSNs usually have very dynamic topology as sensors move passively with water currents. Some routing protocols have been proposed to address the challenging problem in UWSNs. However, most of them assume that the full-dimensional location information of all sensor nodes in a network is known in prior through a localization process, which is yet another challenging issue to be solved in UWSNs. In this report, Directional Vector Forward Focused beam routing (DVFBR) is proposed for UWSN. Former protocols have been compared & constructed with new one. Routing in UWSN will be made more dynamic with this new protocol. Later on performance of newly derived protocol are revised efficiently.
