A Two-Stage Localization Scheme with Partition Handling for Data Tagging in Underwater Acoustic Sensor Networks

Abstract: Knowledge about the geographic coordinates of underwater sensor nodes is of primary importance for many applications and protocols of under water sensor networks (UWSNs) thus making localization of sensor nodes a crucial part of underwater network design. In case of mobile underwater sensor network, location estimation becomes challenging not only due to the need for periodic tracking of nodes, but also due to network partitioning caused by the pseudo-random mobility of nodes. Our proposed technique accomplish… Show more

“…For instance free mobility may introduce network partitioning in which case a set of nodes may not be able to receive localization beacons/neighborhood information and therefore will remain unlocalized. Partition handling mechanisms [33,50], must be investigated to cope up with such situations. Moreover, the prevalent network architectures, which mostly assume fixed reference nodes and limited range stand useless when underwater nodes are unable to communicate with the fixed reference nodes as they move away due to free mobility.…”

“…Location-based routing schemes require location estimates of sensor nodes to determine routes for data forwarding. Location estimation can be achieved using suitable localization services, such as those proposed in [12,13,14,15,16,17,18,19,20,21,22,23]. Table 1 analyzes these protocols based on a number of parameters explained in Section 1.…”

“…Real-time water quality monitoring system using WSNs are popular in recent year because of the advantages of technology to collect data and information through the sensor node. The requirement for continuous data monitoring for water quality in a real-time system to establish the trend and predict to determine behavior from the history as discussed in [5][6][7][8][9]. A biological sensing system for detection water quality is a method to detect bacteria using a computer vision system in analysis, the water pollutant with chemical contamination be able to analysis as discussed in [10][11][12].…”
