Indoor navigation using RF signals has attracted tremendous attention in the recent years. However, indoor localization using RF signaling is very challenging and does not provide adequate precision for many applications. In this paper we use Particle Filter (PF) to integrate the Received Signal Strength (RSS) of WiFi and the Time Of Arrival (TOA) of UWB RF signaling for precise cooperative localization in indoor environment. The choice for PF is due to non-linear and Non-Gaussian channel models for RF localization algorithm. We use channel models for the RSS of WiFi and the TOA of UWB. The performance of the PF results are evaluated in a typical indoor scenario and are compared with the Cramér-Rao-Lower-Bound (CRLB) for Hybrid (UWB & WiFi) in Cooperative (COOP) and non-Cooperative (NCOOP) modes.
To properly acknowledge the individuals who positively impacted my life at WPI, I will resort to using two quotes by David Joseph Schwartz and John Quincy Adams:. .. David Joseph Schwartz: "Here is the basic rule for winning success. Let's mark it in the mind and remember it. The rule is: Success depends on the support of other people. The only hurdle between you and what you want to be is the support of other people." I would like to extend my utmost gratitude to Vice Provost of Research, Prof. Bogdan M. Vernescu who was instrumental in opening a new beginning for my Ph.D. endeavor at WPI. In few occasions that I have had the pleasure of meeting with Prof. Varnescu, he inspired me by his respectful mannerism, his willingness to support, and his sound advice. And more close to home, ECE department, Department Head, Prof. Yehia Massoud resolved my administration issue very quickly and efficiently. I greatly appreciate his whole humble demeanor despite his high scholarly achievements. We have a proverb in IRAN that states: "The more fruitful the tree, the more bent it is" and, on the contrary, a fruitless tree with its light weight stands upright!. .. John Quincy Adams: "If your actions inspire others to dream more, learn more, do more and become more, you are a leader." My advisor, Prof. Kaveh Pahlavan can easily be described by the above quote. With his accomplishment and tenure track for many years, he does not swing his weight against the student and on the contrary, there is no iota of ill-intention towards any student. Under Prof. Pahlavan's leadership, I have greatly benefitted from his selflessness, keenness and visionary ideas. We have shared many laughs and has made this endeavor highly educational and fun. Dedicated to two dearest ladies of my life, my Mother, & my Wife. .. Omar Khayyám, Rubaiyat: "To wisely live your life, you don't need to know much Just remember two main rules for the beginning: You better starve, than eat whatever And better be alone, than with whoever.". . .
This article provides fundamentals of radio frequency (RF) localization techniques. We begin by introducing the basic elements of wireless localization and their associated issues, from location sensors to algorithms and the user interface. Then, we provide models for the RF sensor behavior that include models for received signal strength (RSS), time of arrival (TOA), and the direction of arrival. Next, we introduce Cramer–Rao lower bound (CRLB) for performance evaluation of RF sensors based on the models for behavior of the sensors. Finally, we provide an overview of algorithms used for single‐sensor systems and hybrid localization integrating different sensors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
