Reconfigurable underwater embedded systems architectures

A better-performing Q-learning game-theoretic distributed routing for underwater wireless sensor networks

“…The major contributions of the ELAR scheme are (1) applying the Q-learning technique in a distributed routing protocol for USNs, (2) balancing the workload among sensor nodes for a longer network lifetime, (3) reducing the networking overhead for higher energy efficiency, and (4) learning the environment effectively to improve adaptability in dynamic networks. 14 The work by Sandeep 16 develop a set of underwater embedded system architectures that can handle different network configurations. The idea is to have dynamic architecture that will be configured based on network parameters to achieve best performance in terms of end-to-end delay and power consumption.…”

New Monitoring Architectures for underwater oil/Gas Pipeline using Hyper sensors

“…Accordingly, this paper proposes using "UWSN" wireless network to create a new real time architecture. This network [4], [5], [6] developed by UCONN Research team will act as a pipeline inspection system that combines a real time UWSN sensor network paired with [7] nondestructive In Line Inspection "ILI" technology. The aim of this paper is also to propose why this architecture will reduce pipeline defaults, as this technique will improve data transfer from the pipeline to the processor by extracting useful information and delivering it to the onshore main station, and by doing so, it will decrease delays in default detection.…”

“…The main idea of this architecture is built based on UWSN underwater sensor network which was developed by UCONN. [4], [5], [6] Such a system is used to serve numerus monitoring and detecting applications such as 3-D mapping, fish detection and classification, surveillance, intrusion detection, and military applications that takes place underwater. According to [8] the designed underwater sensor network has a capability to sense, communicate, and forward data form sensor nodes to an offshore control station with less power consumption.…”

“…According to [8] the designed underwater sensor network has a capability to sense, communicate, and forward data form sensor nodes to an offshore control station with less power consumption. The deployment of this architecture [6] has four main components as the following: First, a central computer used to process data, extract valuable information, and then transmit it to the gateway. Second, sensor nodes are used to sense data in its region.…”

“…We studied three communication scenarios for each of the architectures explained above. Figure (4,5,6) shows that each of the architectures can apply to each of these scenarios based on needs. Therefore, we have nine different cases in total.…”
