Research Description

Underwater communication has turned into a prominent research region in deep-sea investigation, undersea navigation, and control of automated underwater vehicles (AUVs). Acoustic communication is the most liable and universally accepted method in underwater medium because of the low attenuation (signal reduction) of sound in water. The operation of underwater acoustic communication (UWAC) structure is rendered challenging by factors such as limited available bandwidth, long propagation delay, huge Doppler spread, time-varying channel conditions, salinity and diverse pressure conditions. The vital applications of Underwater Wireless Sensor Networks (UWSN) are underwater military surveillances and underwater research. The current progressions in innovation, the outline of sensor networks was reborn to a new era of monitoring the global physical entity. These design advancements cleared a path to the disclosure of new unopened insider facts in the field of marine habitats, deep sea environments and ice sheets explorations. This research gives a proficient technique for packet transmission in a selective frequency to enhance the scope and network between the sensor AUV’s which are in observation under secluded ocean. Scientific model is utilized to portray the dynamic changes in the sea. The channel model has been established considering all the channel properties under the sea. The AUVs are connected to a cluster-based network and an efficient cluster-based routing protocol (CBRP) is used to convey the 3-D location of the AUVs. By selecting an optimum frequency for transmitting the routing packets, overall life time of the network is extended with least routing delay. CBRP Technique is utilised to limit the channel impairments as a result of its vigour against excessively restricted transmission capacity and recurrence reuse. The simulation results of the proposed algorithm show better connectivity and coverage between the surveillance AUVs and to communicate their location with one another.
