Abstract
Internet of Things enabled Underwater Wireless Sensor Networks (IoT-UWSNs) are quite useful in monitoring different tasks including: from instrument monitoring to the climate recording and from pollution control to the prediction of natural disasters. However, there are some challenges, which affect the performance of a network, i.e., void hole occurrence, high Energy Consumption (EC) and low Packet Delivery Ratio (PDR). Therefore, in this work, two energy efficient routing protocols are proposed to maximize the PDR by minimizing the ratio of void hole occurrence. Scalability analysis of the proposed routing protocols is also performed. Additionally, feasible regions are computed to check the optimality of the proposed protocol in terms of EC. Furthermore, proposed protocols are compared with benchmark routing protocols in counterparts. Simulation results clearly show that proposed routing protocols achieved 80-81% higher PDR than GEographic and opportunistic routing with Depth Adjustment based topology control for communication Recovery (GEDAR) and Transmission Adjustment Neighbor-node Approaching Distinct Energy Efficient Mates (TA-NADEEM). Moreover, the ratio of void hole occurrence is minimized upto 30% approximately.

Internet of Things enabled Underwater Wireless Sensor Networks (IoT-UWSNs) help in monitoring natural disasters and the aquatic environment
SIMULATION AND RESULTS Im-GEDAR and Co-Im-GEDAR are evaluated by performing extensive simulations for benchmark routing protocols (GEDAR, Weighting Depth Forwarding Area Division (WDFAD)-DBR, node Approaching Distinct Energy Efficient Mates (NADEEM), FA-NADEEM and TA-NADEEM)
Packet Delivery Ratio (PDR) is higher than NADEEM because of its better neighbors selection strategy and holding time to avoid the redundant transmissions, which enables the WDFAD-DBR towards better network lifetime and improved PDR than NADEEM
Summary
Internet of Things enabled Underwater Wireless Sensor Networks (IoT-UWSNs) help in monitoring natural disasters and the aquatic environment. Considering the aforementioned limitations, GEographic and opportunistic routing with DA based topology control for communication Recovery (GEDAR) is one of the useful UWSN routing protocols, which minimizes the EC with high Packet Delivery Ratio (PDR). It faces void hole [2]. (because they have high energy and assure the maximum monitoring of the network field) They perform Transmission Range Adjustment (TRA) to minimize the fraction of the void nodes occurrence and overcome the dynamically changing network topology.
