Underwater wireless sensor network has been an area of interest for a few previous decades. UWSNs consists of tiny sensors responsible for monitoring different underwater events and transmit the collected data to the sink node. In the harsh and continuously changing environment of water, gaining better communication and performance is a difficult task as compared to networks available on land because of different underwater characteristics such as end-to-end delays, node movement, and energy constraints. In this paper, a novel routing technique named angle adjustment for vertical and diagonal communication was proposed, which doesn't use any location information of nodes. It is also efficient in terms of energy and end-to-end delays. In this approach, the source node evaluates the flooding zone based on the angle by using the basic formula for forwarding the packet to the sink. After evaluating the flooding zone, the angles of each node are compared and the packet is sent to the node closest to the vertical line. The proposed approach is evaluated with the help of NS-2 with AquaSim. The results show better results performance in data delivery, end-to-end delays, and energy consumption than DBR.

“…The connectivity of any ad hoc network is highly dependent on the mobility model it follows. As per the previous study mentioned in [41][42][43], the random way mobility model is widely used to simulate the performance of any mobile ad hoc network such as [44][45][46], fixing the source and sink nodes at the bottom and surface of the water, respectively, with coordinates (80, 90,100) and (10,20,30). To calculate the value of energy consumption, we use the 'Tx' Power 'Rx' Power and 0.007 W, respectively.…”

Conventional underwater technologies were not able to provide authentication and proper visualization of unexplored ocean areas to accommodate a wide range of applications. The aforesaid technologies face several challenges including decentralization, beacon node localization (for identification of nodes), authentication of Internet of Underwater Things (IoUTs) objects and unreliable beacon node communication between purpose oriented IoT-enabled networks. Recently, new technologies such as blockchain (BC) and the IoUTs have been used to reduce the issues but there are still some research gaps; for example, unreliable beacon messages for node acquisition have significant impacts on node identification and localization and many constrained node resources, etc. Further, the uncertainty of acoustic communication and the environment itself become problems when designing a trust-based framework for the IoUTs. In this research, a trust-based hybrid BC-enabled beacon node localization (THBNL) framework is proposed to employ a secure strategy for beacon node localization (BNL) to mine the underwater localized nodes via the hybrid blockchain enabled beacon node localization (HB2NL) algorithm. This framework helps to merge two disciplines; it is hybrid because it follows the nature and bio inspired meta heuristics algorithms for scheduling the beacon nodes. The performance of the proposed approach is also evaluated for different factors such as node losses, packet delivery ratios, residual and energy consumption and waiting time analysis, etc. These findings show that the work done so far has been successful in achieving the required goals while remaining within the system parameters.

“…Another reason for a void hole in the network is the continuous and random movement of nodes in the I-UWSAN that cannot be neglected [6]. Three-dimensional (3D) dynamic topology also affects the performance of an underwater network and has been analyzed through diagonal and vertical paths for data transmission in underwater networks in [7]. It is assumed that in the underwater environment (at the time of deployment) that nodes will be static and cannot move, but in fact, nodes can move 2 m/s to 3 m/s due to the volatile nature of the environment.…”

More than 70% of the Earth's surface is covered by water. Internet of Things (IoT) based underwater sensor and actor networks have good potential to explore this water-covered area. Underwater wireless sensor networks (UWSNs) have attracted researchers from industry and academia for exploring underwater resources by enabling a variety of applications such as aquatic environment monitoring, disaster prevention, pollution monitoring, mineral extraction, flood and tsunami warning, and military defense [1]. A specified geographic volume is covered with randomly deployed sensor nodes with the ability to sense, gather, and forward data toward the destination (the sink) [2].
