Underwater wireless sensor network (UWSN) has emerged as one of the most popular network technologies owing to its applicability to offshore searches, and underwater monitoring and exploration applications. It has been shown to be useful in the fields of investigations and surveillance, and in assisting with and offering solutions to water-based calamities. Reliability in the underwater environment has caused researchers to direct attention towards improving the overall efficiency and energy utilisation of the network. In the present paper, reliable node quester (RNQ) algorithm has been formulated to calculate the node reliability for numerous parameters such as success rate, transmission time, and the affordability, congestion and stability of the nodes. The present paper highlights the data-forwarding mechanism of the nodes to enhance overall network reliability by (i) reducing the packet drop rate; (ii) increasing the packet delivery ratio; and (iii) minimising the energy consumption. Simulation results further support the proposed strategy by ensuring the network lifespan and detection accuracy.
