Relative Localization of Wireless Sensor Nodes by Using the RSSI and ToA Based Distance Estimations

Öz:
Wireless sensor networks (WSNs) consist of multiple sensor nodes connected via wireless infrastructures, such as Wi-Fi, Bluetooth, ZigBee, and WiMAX. Determining the relative or absolute positions of these nodes is crucial for various applications. In this study, an improved method for estimating the position of WSN nodes is presented that combines the estimation results of the Received Signal Strength Indicator (RSSI) and Time of Arrival (ToA) metrics from the preferred wireless communication infrastructure. Results of the position estimation are compared based on both measurements and distance between the nodes. The proposed method uses position estimations based on both RSSI and ToA metrics, but the result of a single method is favored depending on the distance between nodes, with RSSI being superior for short distances and ToA for farther distances. The results demonstrate that the proposed combined method reduce estimate errors and perform better than either method alone.

RSSI ve ToA Tabanlı Mesafe Tahminlerini Kullanarak Kablosuz Sensör Düğümlerinin Bağıl Lokalizasyonu

Öz:
Kablosuz sensör ağları, Wi-Fi, Bluetooth, ZigBee ve WiMAX gibi kablosuz altyapıları kullanarak bağlanan birçok sensör düğümünden oluşur. Sensör düğümlerinin göreli veya mutlak konumlarının belirlenmesi birçok uygulama için önem taşımaktadır. Sunulan çalışmamızda, tercih edilen kablosuz iletişim altyapısının Alınan Sinyal Gücü Göstergesi (RSSI) ve Varış Zamanı (ToA) metriklerinden elde edilen sonuçları birleştirerek sensör nodlarının konumunu daha yüksek başarımlı tahmin etmek için geliştirilmiş bir yöntem sunulmaktadır. Konum analizinin sonuçları ölçümlere ve nodlar arasındaki mesafelerin karşılaştırmasına dayanarak sunulmaktadır. Önerilen yöntem RSSI ya da ToA verilerine dayalı kestirim sonuçlarını düğümler arasındaki mesafeye göre tercih etmektedir, kısa mesafelerde RSSI uzak mesafelerde ise ToA tercih edilmektedir. Sonuçlar, bileşik yöntemin tahmin hatalarını azalttığını ve her iki yöntemden de daha iyi performans sergilediğini göstermektedir.
