Energy Efficient Crypto Suit for Secure Underwater Sensor Communication using Genetic Algorithm

With the advancement in technology, there has been a keen interest of researchers and industrial institution in the use of Underwater Sensors Networks (UWSN). This study is devoted to the secure communication between the underwater sensors networks which is now a day’s most widely used for oceanographic abnormalities, and to track submarines that perform the surveillance and navigation. But UWSNs has its limitations such as multipath, propagation delay, low bandwidth, and limited battery as compared to traditional WSNs that causes a low life in comparison with WSNs. Secure communication in UWSNs is more difficult due to the above-mentioned limitations which need ultralightweight components. There are many miscellaneous attacks due to which sensors can be able to lose both data availability and integrity that is why this study is basically to design an efficient algorithm that possesses less computation and use less space for secure communication. The proposed algorithm will initially establish the first half of the key through a genetic algorithm and then will develop the remaining part. After that encryption algorithm is proposed for the secure communication between UWSNs and its performance will be evaluated based on throughput, running time, space usage, and avalanche effect.

A SURVEY ON UNDERWATER WIRELESS SENSOR NETWORKS REQUIREMENTS

Underwater wireless sensor networks are currently conducting substantial research in a different environment for benefit of humans. UWSNs are known to be one of the fastest-growing technical fields, due to the many advantages of their application. UWSNs consist of underwater sensors with minimal resources and use the acoustic connection as a communications medium. Current technical advancements have given rise to opportunities for underwater exploration by using sensors at all levels. However, this article provide an overview of the major requirements of UWSNs to accomplish the crucial services. This article also provides an overview of underwater wireless communications.

Propuesta de un sistema de comunicación inalámbrico para una red de sensores bajo el agua en tiempo real aplicado a un sistema ROV

This work a novel approach in radio frequency communications applied to a underwater wireless sensors network UWSN is presented. The proposal is to manipulate in a bounded and controlled environment a Remote Operated Vehicle ROV without umbilical cable through a underwater sensors network based on radio frequency communication, taking advantage of the faculties of this underwater communication in conjunction with a sensor network, furter, a dynamic redundancy is used in the transmitters towards the ROV to increasing the range and avoiding communication loss, aditional a static redundancy is applied on the receiver to increase te reliability of comunication. The part of the ROV receiving sensors is based on a statisc redundancy of 3 sensors which will apply a vote taking in order to failure tolerantce, the sensor network will applied a dinamic redundacy in the transmitters in order to follow the communication with the ROV, in case of failure, the communication loss can be compensated with another sensor of the network that will take its role.
