Robust Localization Based on Measurement Reliability

As the key technology, localization is a fundamental research that has been extensively studied in the literature of wireless sensor networks. Improving the accuracy and decreasing the costs of localization is the mainly goal for node localization. To improve the precision of located nodes, we design the wTLS localization approach, which relies on the distance reliability and makes good use of the distance information. Based on the variance of different hop counts, we apply the approach to DV-Hop localization. The experiment results show that wTLS outperforms the state-of-arts approaches with high accuracy, efficiency, and consistency of performance and gains more excellent results than TLS and LS.
