Simulation Study of Nodes Deployment of Underwater Sensor Network Based on Reliability Coverage Algorithm

Abstract

Abstract: For 3D nodes-deployment of the underwater sensor networks, the definitions of detection reliability and reliability coverage was proposed. According to the advanced D-S theory of evidence, the change of reliability coverage in underwater sensor networks' detection area was analyzed, and a Nodes-deployment Algorithm Based on Advanced D-S Theory of Evidence and Prior Probability (NAAEP) combining with the prior probability of target nodes distribution was proposed. The value of the target perceived reliability was transformed into a virtual potential field force that a node was suffered in size, and the position of the nodes was adjusted according to the force that nodes were suffered in potential field. Simulation model of underwater sensor networks was established using MATLAB. The simulation results show the effectiveness of the algorithm, energy consumption and the number of deployment nodes is reduced, and the scope of perceiving is expanded. As a result, NAAEP can improve the detection performance of the network.
