Differentiated Underwater Sensor Network Deployment

Abstract

International audienceUnderwater sensors technology has experienced a tremendous development over the last decade. They have generated considerable community enthusiasm, which applied them to a wide range of cases that could enhance human and animal habitat conditions e.g. climate changes prediction or pollution surveillance. In this paper, we address the issue of deploying a UWSN in an area characterized by the geographical irregularity of the sensed event. Our specific application context regards the monitoring of the water quality in a small closed area (e.g. a lake). For this purpose, we propose a differentiated deployment algorithm (DDA) based on a mesh representation method inspired from the image processing and 3D modeling field

Comparison of Localization Free Routing Protocols in Underwater Wireless Sensor Networks

“…Furthermore, acoustic channels also required more energy for communication than terrestrial network [21], [22]. Batteries in UWSN cannot be recharged or replaced therefore use of energy efficient communication is always required to provide network with higher life time [14].…”

“…The number of dolphin nodes depend upon the kind of network and its application and the number of nodes deployed in the network. In [22], a virtual sink architecture is proposed where sinks are connected with each other through radio communication. In this scheme, each and every sink broadcast a hello packet which is also known as hop count update packet.…”

“…These protocols perform their operation without having location information of other nodes. In these kind of routing protocols, a sensor node does not require any prior network information of other network nodes [22], [14]. Most of the localization protocols work on flooding phenomenon and are considered to have fast packet delivery ratio and low end to end delay [14], [20].…”

A power-efficient routing protocol for underwater wireless sensor networks

“…Based on a mesh representation method inspired from the image processing and 3D modeling field, a differentiated deployment algorithm (DDA) was proposed in [27]. It deployed UWSNs in an area characterized by the geographical irregularity of the sensed event.…”

Mobile-MultiSink Routing Protocol for Underwater Wireless Sensor Networks

“…A number of issues need to be addressed while using UWSNs. Different from terrestrial sensor networks, the underwater scenario poses some challenges, like high transmission delay, nodes' irregular movement, varying network topology and frequent loss of connectivity due to underwater currents [1,2,4,10,14,18]. Therefore, conventional routing protocols are not appropriate for UWSNs.…”
