Résumé

This paper is concerned with localization in wireless sensor networks (WSNs). We propose a novel localization algorithm based beamforming. The performed localization algorithm is adopted for a typical communication model in WSNs involving two clusters of sensors at both transmitter and receiver sides of the communication link. The set of collaborative sensor nodes located at the transmit cluster could be assimilated to a distributed Multiple Input Multiple Output (MIMO) system [1], [2], [3]. We tackle the task of estimating the position of randomly distributed sensor nodes and we present a novel algorithm based on the beamforming approach [4], [5] and the received signal strength (SS) measurement. The correct operation of the proposed algorithm has been proved by simulation. The collected results for the sampling deviation of the estimator and the estimator variance are envisaged in order to evaluate the accuracy of the proposed algorithm.
