“…The forwarding node waits for a specified period, which is proportional to its depth to avoid the involvement of multiple nodes to forward the same packet. Later, many depth-based power-efficient protocols [3,5,48,49] have been proposed to address the challenges of the underwater sensor network (UWSN). However, extra battery power is required to estimate the depth of a node in such routing methods.…”

The Internet of Things (IoT) has facilitated services without human intervention for a wide range of applications, including underwater monitoring, where sensors are located at various depths, and data must be transmitted to surface base stations for storage and processing. Ensuring that data transmitted across hierarchical sensor networks are kept secure and private without high computational cost remains a challenge. In this paper, we propose a multilevel sensor monitoring architecture. Our proposal includes a layer-based architecture consisting of Fog and Cloud elements to process and store and process the Internet of Underwater Things (IoUT) data securely with customized Blockchain technology. The secure routing of IoUT data through the hierarchical topology ensures the legitimacy of data sources. A security and performance analysis was performed to show that the architecture can collect data from IoUT devices in the monitoring region efficiently and securely.

“…Although in order to achieve extended network lifetime, some packets are dropped. On the avoidance of coverage hole area and energy hole in underwater networks [6], gave solution by coverage repair algorithm and balanced energy consumption techniques. This scheme suffers from packet delivery ratio to achieve prolong network life time, energy consumption and throughput.…”

Energy is a unique characteristic of Underwater Acoustic Sensor Networks (UASNs) which is limited in features and a basic point on which the whole network depends. On the basis of efficient energy utilization, we propose a routing protocol Enhanced and Efficient Balance energy consumption in Data Gathering (EEBDG) for UASNs. This routing scheme EEBDG, works for large scale area networks efficiently and effectively by balanced energy consumption. EEBDG removes the deficiency of previous routing scheme in which mixed routing performs all over the network which is not possible in real world when network size increases. By the increase in area of a network, we avoid the direct transmission mode using only hop by hop transmission. The contribution of our work is to extend network lifetime with large scale in the form of increased nodes and dimension, minimize energy utilization by balanced energy consumption, increased number of packets transfer. Our trade-off is packet drop ratio when number of nodes is small in sparse networks, but when the number of nodes increases our packets drop is also improved.

In this paper, we propose two schemes; position-aware mobility pattern (PAMP) and cooperative PAMP (Co PAMP). The first one is an optimization scheme that avoids void hole occurrence and minimizes the uncertainty in the position estimation of glider’s. The second one is a cooperative routing scheme that reduces the packet drop ratio by using the relay cooperation. Both techniques use gliders that stay at sojourn positions for a predefined time, at sojourn position self-confidence (s-confidence) and neighbor-confidence (n-confidence) regions that are estimated for balanced energy consumption. The transmission power of a glider is adjusted according to those confidence regions. Simulation results show that our proposed schemes outperform the compared existing one in terms of packet delivery ratio, void zones and energy consumption.
