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

Abstract

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 in UWSN, they have a large amount of delay, easily error-prone, low availability of bandwidth and high congestions control. In this paper, we propose a mechanism that addresses the reliability of the network by adapting two-hop acknowledgement (2H-ACK) models. Enhancement of the model is carried out to make it congestion-free by integrating the hybrid approach into the existing protocols. By this enhanced model, it shows that the performance of the model is good when compared to the existing ones in terms of delay, error rate, bandwidth and congestion. Simulation outcomes prove that the 2H-ACK proves to be best in delivery ratio when checked with the existing hop by hop acknowledgement.
