Wireless sensor network for underwater communication

IET Conference on Wireless Sensor Systems (WSS 2012), 2012
Although, attenuation in Electromagnetic (EM) wave propagation underwater is high at high frequencies, the theory predicts that propagation is possible at some useful distance in the lower Industrial, Scientific and Medical (ISM) band. The aim of this paper is to study the feasibility of using radio transceivers underwater for developing a Wireless ...

Smart underwater wireless sensor networks

2012 IEEE 27th Convention of Electrical and Electronics Engineers in Israel, 2012
In the last years, with the flourishing of the WSN (wireless sensor network) paradigm, the monitoring and exploration of the terrestrial environment has greatly improved. While terrestrial and aerial WSN applications have been developed, the aquatic world has been unaffected by this revolution, although WSN could play an important role in the ...

Secure communication in mobile underwater wireless sensor networks

2015 International Conference on Advances in Computing, Communications and Informatics (ICACCI), 2015
Underwater sensor networks (UWSN) provide a promising solution for several aquatic applications. Mobile UWSNs are vulnerable to various threats because of their harsh environment, acoustic communication channel, bandwidth limitation, high propagation delay, multipath effect, and mobility. Therefore, appropriate security mechanisms should be included in

A Trust Cloud Model for Underwater Wireless Sensor Networks

IEEE Communications Magazine, 2017
Nowadays, the study of underwater WSNs (UWSNs) has become a hot topic. However, UWSNs have not been fully utilized in the complex underwater environment, since there are some difficulties in controlling mobile sensor nodes and underwater environment conditions.

Deployment analysis in underwater acoustic wireless sensor networks

Proceedings of the 1st ACM international workshop on Underwater networks - WUWNet '06, 2006
In this paper, different deployment strategies for two-dimensional and three-dimensional communication architectures for UnderWater Acoustic Sensor Networks (UW-ASNs) are proposed, and statistical deployment analysis for both architectures is provided. The objectives of this paper are to determine the minimum number of sensors needed to be deployed to ...

A survey on routing techniques in underwater wireless sensor networks

Journal of Network and Computer Applications, 2011
Underwater Wireless Sensor Networks (UWSNs) are finding different applications for offshore exploration and ocean monitoring. In most of these applications, the network consists of significant number of sensor nodes deployed at different depths throughout the area of interest. The sensor nodes located at the sea bed cannot communicate directly with the

Power-Aware Routing for Underwater Wireless Sensor Network

2014
Water covers more than 70 % of the entire planet, contains much of its natural resources. With the increasing use of underwater sensors for the exploitation and monitoring of vast underwater resources, underwater wireless sensor network (UWSN), mostly based on acoustic transmission technologies, have been developing steadily in terms of operation range

A Distributed Clustering Scheme for Underwater Wireless Sensor Networks

2007 IEEE 18th International Symposium on Personal, Indoor and Mobile Radio Communications, 2007
Underwater wireless sensor networks (UWSNs) pose many challenges due to the intrinsic properties of underwater environments such as large propagation delays, node mobility and limited bandwidth capacity of acoustic channels. In this paper we present DUCS (distributed underwater clustering scheme), a new GPS-free routing protocol for UWSNs that does not

A Reliable Data Flooding in Underwater Wireless Sensor Network

2013
The problem of data gathering in the inhospitable underwater environment, besides long propagation delays and high error probability, continuous node movement also makes it difficult to manage the routing information during the process of data forwarding.
