Abstract: The WSNs (Wireless Sensor Networks) lead to great opportunities to explore it scientifically. In thisnetwork different numbers of SN (Sensor Nodes) are deployed in a specific area to gather information.The UWSNs (Underwater Wireless Sensor Networks) is a highly distributed network of sensor nodesdeployed underwater to gather environmental information. Hence, acquirement of real-time data atenhanced data rate and to reduce power consumption is a key concern while designing routing protocolfor UWSNs. In this paper, a cooperation based solution is suggested. The solution proposed here uses theDF (Decode and Forward) strategy for relying the information from the source to the destination using arelay node. The signals coming towards the destination are weighted and combined on the basis of theirSNRC (Signal to Noise Ratio Combing). The simulation results verify enhancement in different factors,required for evaluation of a UWSN. After implementation of the proposed solution the stability of thenetwork is increased which maximize the PDR (Packet Delivery Ratio). In our proposed solution thetransmission is based on channel estimation, an estimate is made for higher reliable channel, whichreduces retransmission of packets. Hence, sink receive the packets with lesser delay and as a result E2E(End-to-End) delay is decreased. Data is forwarded using data forwarding by neighbor nodes. It improvesaverage energy consumption of the system. Hence the overall performance and lifetime of a UWSN isincreased.
