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 ...

Introduction to Underwater Wireless Sensor Networks

2021
“Sensor networks” can be said as a significant part of technology that creates magic of sensing and wirelessly sending information on land and in water. Sensor networks built on land are popularly named as terrestrial sensor networks which are used in many applications from IoT, VANET to smart cities. The underwater wireless sensor networks [UWSNs] are

Firewall in Underwater Wireless Sensor Networks

2021
In this technological arena, a firewall is a major tool for network security system to predetermine its basic rules so that it can control and monitor incoming and outgoing network traffic. The firewall generally restricts the faulty and unusual data entering the system. It can be categorized as host-based firewalls and network-based firewalls.

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.

Energized geocasting model for underwater wireless sensor networks

Simulation Modelling Practice and Theory, 2013
Abstract In sensor networks, energy plays a vital role during communication between the sensor nodes. The amount of energy available at a sensor node increases or decreases the life of the network. A group of sensor nodes can share their information, only when they are active and alive that is they have enough energy to communicate. Over the past few

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 ...
