A Distributed Localization Scheme Based on Mobility Prediction for Underwater Wireless Sensor Networks
A distributed localization scheme based on mobility prediction for mobile underwater wireless sensor networks is proposed.Anchor nodes perform self-localization and mobility prediction,and serve as reference nodes to localize ordinary nodes.According to the group movement properties of underwater objects,ordinary nodes perform self-localization by utilizing the neighboring nodes locations and their predicted speed vectors.Well-localized ordinary nodes serve as reference nodes to localize neighbors further.The modified covariance algorithm is employed to estimate the linear prediction parameters of the mobility pattern.A Node-Selection Strategy is proposed to select the most suitable reference nodes to localize an ordinary node.The simulation results demonstrate the advantages of the proposed scheme.
