Node localization algorithm of wireless sensor network in marine monitoring

Focusing on the applications of wireless sensor networks in marine monitoring,a localization algorithm of sensor nodes based on Monte Carlo was proposed.The algorithm improved the location accuracy of the prediction stage by introducing the right angle of the sea motion;and revised the prediction coordinates by the confidence of the prediction coordinates which was gained through the node's perception of pressure.The simulation results show the proposed algorithm has outstanding performance compared with traditional methods under conditions of different node density,seed density,moving speed and time.
