Robust Localization Based on Measurement Reliability
As the key technology, localization is a fundamental research hotspot that has been extensively studied in the literature of wireless sensor networks. Improving the location.accuracy and. realize the location optimization is the mainly goal for node localization. For improving the precision of sensor node location, designing wTLS localization approach, which relies on the distance reliability and makes good use of the distance information. According to the different variance value of hop counts in DV-Hop, applying the approach in DV-Hop can improve the accuracy of node effectively. The experiment results show that wTLS outperforms the state-of-arts approaches with high accuracy, efficiency, and consistency of performance and gains more excellent result than TLS and LS.
