Cette lettre présente la variation de l'erreur de localisation par rapport aux paramètres du réseau, le nombre de résultats d'estimation de portée à partir des nœuds d'ancrage (AN) et la distance moyenne entre les AN dans un réseau de capteurs sans fil (WSN) centralisé. Dans le réseau de capteurs, les AN estiment la distance relative par rapport au nœud cible (TN) à l'aide des informations d'heure d'arrivée (TOA) de la radio Ultra WideBand (UWB) et un centre de fusion détermine la localisation finale du TN sur la base des résultats d'estimation rapportés. À partir des résultats de simulation, la variation de l'erreur de localisation, qui est définie comme la différence entre le résultat de localisation du TN et son emplacement réel, est représentée en fonction du nombre de résultats d'estimation par rapport à la distance moyenne entre les AN. La distribution de l'erreur de localisation correspond à la distribution de Rician dont la valeur du facteur K est également donnée par la formule proposée. Enfin, la fonction d'erreur normalisée pour la conception efficace d'un réseau de localisation est caractérisée.

Abstract: This letter presents the variation of localization error to network parameters, the number of range estimation results from anchor nodes (ANs) and average distance between ANs in centralized Wireless Sensor Network (WSN). In sensor network, ANs estimate the relative range to Target Node (TN) using Time-Of-Arrival (TOA) information of Ultra WideBand (UWB) radio and a fusion center determines the final localization of TN based on estimation results reported. From simulation results, the variation of localization error, which is defined as the difference between localization result of TN and its actual location, is represented as the function of number of estimation results to average distance between ANs. The distribution of localization error is matched to the Rician distribution whose K-factor value is given by the proposed formula as well. Finally, the normalized error function for the efficient localization network design is characterized.
