| A passive solution for indoor positioning of Wi-Fi devices has been recently proposed in the literature [1], which merges a time-difference of arrival (TDOA) algorithm with the novel fine time measurements (FTM) introduced in IEEE 802.11mc (aka Wi-Fi RTT, Round-Trip-Time). The approach leverages the scalability limitation of the original Wi-Fi RTT procedure. By exploiting other IEEE 802.11mc devices performing their own location with neighbour APs, passive Wi-Fi RTT is able to locate all devices on a network at once without injecting additional location traffic. This same idea has been also adopted in Next Generation Positioning (NGP), the new IEEE 802.11az released in 2023.
A proof of concept of the Wi-Fi passive TDOA algorithm was simulated in Matlab [1], and the impact of the error on the ranging estimations was assessed. However, the recent release of the FTM-ns3 module, an extension for the widely used ns3 network simulator to support the Wi-Fi RTT protocol, paves the way for a deeper analysis of the Wi-Fi RTT passive approach. The idea of this master thesis is to implement the passive Wi-Fi RTT approach in ns3. The goal is to analyse the impact of several sources of error on the precision of the final position estimate of the passive user in more realistic scenarios (e.g., line of sight, multipath, etc.).
