Abstract
Due to malicious anchor nodes in the three dimensional underwater sensor nodes, effective localization based routing algorithm under malicious anchor has been considered as importance of the particular research. Many traditional localization based routing model has been implemented for monitoring activities on the acoustic network, despite of many advantage of the location based routing technique, still many challenge has been continuing in terms of coverage and connectivity. In order to tackle those challenges, a new localization based protocol named as Malicious Anchors Voting based Error Specific Localization Algorithm has been proposed to Underwater Acoustic Sensor Network under Doppler Effect and multipath propagation. In this work, error specific localization of the nodes has been applied as one of the important technique that increases system scalability and reduces attacks propagating in the sensor nodes. The proposed model decide the proper detection and communication of events of interest in UWSN due to unstable underwater environment by reducing irrelevant attack features in the trace file on utilizing multiple voting mechanism on the nodes such as Clock Synchronization , motion of the sensor nodes, distance between the sink node and sensor node. On computation of those information’s, malicious anchor nodes have been localized. Those localized node are further processed using Cooperative localization for determining maximum localization coverage ranges for data communication on association weight using reputation mechanism. Trust based authentication has ability to adapt to the changes of the distance value during data communication on multi hop communications using localization function on weighted average of nodes Reputation scheme. On simulation analysis on Matlab, proposed model has been compared with existing schemes to demonstrate the effectiveness of the proposed scheme especially in detecting and preventing malicious anchor node and providing good communication and networking performances in terms of Average Localization Error with Inconsistent Malicious Anchor, Average Localization error with inconsistent distance threshold, Localization coverage Ratio and program running time. Finally it has been proved that proposed model attains better benefits on both localization coverage ratio and Localization Error with Inconsistent Threshold node to produce the effective localization in underwater environment.
