Descripció del contingut i pla d'activitats:
Few years ago, Google included IEEE 802.11mc technology in Android O.S. This amendment was intended to provide positioning capabilities to the Wi-Fi network so that indoor positioning, where GPS is known not to work properly, becomes possible. Thus, Android devices are able to compute the distance from their location to the place the access points (APs) are positioned.

FTM-ns3, an extension for the widely used ns3 network simulator to support the 802.11 FTM protocol, has been recently released. This extension supports three error models, which are based on the results from extensive lab experiments from the same authors with real FTM hardware. The tool allows to analyse the impact of channel bandwidth and channel propagation characteristics on the performance of FTM-based ranging or localization schemes in a controlled simulation environment.

FTM-ns3 lacks an error model capable of reproducing the behaviour observed in current commercially available smartphones (COTS) that implement Wi-Fi RTT capability, which are one of the main targets of IEEE 802.11mc technology. Furthermore, only 20 MHz and 40 MHz channels are currently considered by FTM-ns3. Several studies performed with such devices show that a Gaussian behaviour is not observed in real smartphones.

The main goal of this master thesis is to infer and implement, in the FTM-ns3 extension, the error model that we have derived in our previous work. Two approaches will be followed: an empirical model obtained from experimental observations, and a fitting model based on goodness-of-fit tests.

Objectives:
1) Check that the FTM-ns3 extension does work properly in the newly released version of the simulator.
2) Update it to the last ns-3 version, if required.
3) Derive an error model from our recent experiments with COTS Android devices.
4) Implement the new error model in the FTM-ns3 extension.
5) Assess a thorough validation of the implementation.
