UNDERWATER ACOUSTIC SENSOR NETWORKS (UW-ASN )
[attachment=41634]
INTRODUCTION
Ocean bottom sensor nodes are deemed to enable applications for oceanographic data collection, pollution monitoring, offshore exploration, disaster prevention, allocating resources and tactical surveillance applications.
To make these applications viable, there is a need to enable underwater communications among underwater devices.
These sensor communicate through acoustic waves which are a type of longitudinal waves that propagate by means of adiabatic compression and decompression.
UnderWater Acoustic Sensor Networks (UW-ASN) consist of a variable number of sensors and vehicles that are deployed to perform collaborative monitoring tasks over a given area.
SENSORS used
Group of sensors and vehicles deployed underwater and networked via acoustic links, performing collaborative tasks
Equipments used
Autonomous Underwater Vehicles (AUVs)
Underwater sensors (UW-ASN)
OBJECTIVES
UNDERWATER ACOUSTIC SENSOR NETWORKS
To exploit multi hop paths
oceanographic data collection
pollution monitoring, disaster prevention etc.
AUTONOMOUS UNDERWATER VEHICLES
autonomous coordination obstacle avoidance
CONCLUSIONS
The ultimate objective of this paper is to encourage research efforts to lay down fundamental basis for the development of new advanced communication techniques for efficient underwater communication and networking for enhanced ocean monitoring and exploration applications.
