Abstract

Abstract:

In order to effectively overcome the contradiction between the accuracy of node localization and the complexity of ranging technology in wireless sensor network（WSN）,a new dummy array node selection method sui-table for localization is proposed based on the random distribution of WSN and the restricted geometry structure of sensor array.In this method,the dummy sensor array based on node cooperation is used to locate the sensor nodes in WSN.Simulated and analyzed results indicate that,when the estimation algorithm of the direction of arrival meets the capability requirements,the proposed method is feasible and accurate in localization.

Key words: sensor network, antenna array, global node selection, localization
