Energy efficient congestion free and adaptive mechanism for data delivery in underwater wireless sensor networks using 2H-ACK

Underwater Wireless Sensor Networks (UWSN) seems to be a significant area of research as it gives out the proper answer for monitoring uneven circumstances that may result and bring forth scare in human existence. The challenging process UWSN, they have large amount delay, easily error-prone, low availability bandwidth high congestions control. In this paper, we propose mechanism addresses reliability network by adapting two-hop acknowledgement (2H-ACK) models. Enhancement model is carried make congestion-free integrating hybrid approach into existing protocols. By enhanced model, shows performance good when compared ones terms error rate, congestion. Simulation outcomes prove 2H-ACK proves best delivery ratio checked with hop acknowledgement.
