Coastal surveillance networks using AVS and blue green lasers

The current work is based on the original paper [1] on the use of Acoustic Vector Sensors (AVS) in sensor networks for coastal underwater surveillance. However, this paper explores the feasibility of using blue green lasers as an alternate means of underwater communication in sensor networks which is currently limited to the use of underwater acoustics. The aim of this paper is to provide a simplistic view on a conceptual UW AVS based sensor network employing blue-green lasers that could be used for coastal surveillance in the Indian coastline. The paper is based on the underwater sensor network topology previously proposed by the authors in [1]. It is assumed that the reader has the basic knowledge of underwater sound propagation especially in shallow oceans.
