Ubiquitous positioning provides continuous positional information in both indoor and outdoor environments for a wide spectrum of location based service (LBS) applications. With the rapid development of the low-cost and high speed data communication, Wi-Fi networks in many metropolitan cities, strength of signals propagated from the Wi-Fi access points (APs) namely received signal strength (RSS)...

Pervasive positioning provides uninterrupted positional information in both indoor and outdoor locations for a wide spectrum of location based service (LBS) applications. With the rapid enlargement of the low-cost and high speed data communication, Wi-Fi networks in many metropolitan cities, strength of signals broadcasted from the Wi-Fi access points (APs) namely received signal strength (RSS)...

WiFi-based indoor localization using the fine time measurement (FTM) protocol has become a popular technique. However, in harsh Non-Line-of-Sight (NLoS) environments, WiFi FTM positioning (WFP) suffers from poor performance. In this letter, novel method with assistance of geomagnetic (GP) is proposed. To ensure accuracy GP, an enhanced mind evolutionary algorithm (EMEA) designed. A fine-grained...

The Fisher information (FI) measure is an important concept in statistical estimation theory and information theory. However, it has received relatively little consideration in image processing. In this paper, a novel algorithm is developed based on the nonparametric FI measure. The proposed algorithm determines the optimal threshold based on the FI measure by maximizing the measure of the sepa...

In this paper a fuzzy logic (FL) based load frequency controller (LFC) called discrete FuzzyP+FuzzyI+FuzzyD (FP+FI+FD) is proposed to ensure the stability of a multi-source power system in restructured environment. The whale optimization algorithm (WOA) is used for optimum designing the proposed control strategy to reduce fuzzy system effort and achieve the best performance of LFC task. Further...
