simMLE.m: Simulation script and accompanying functions which run simulation trials for sensor localization when measurements are RSS and TOA. The simulation generates a sensor network geometry, selects reference devices, generates measurements based on the statistical models presented in [1], and then estimates sensor coordinates by maximizing the likelihood function. Many trials are run, and afterwards, the 1-standard deviation uncertainty ellipse of the simulations is ouput. The Cram¨r-Rao bound (CRB) is also calculated and displayed. calcLocalizationCRB.m: Function for calculation of the CRB on unbiased location estimators. This code calculates the bound when measurements are either RSS, Quantized RSS, Proximity (Connectivity), TOA, or AOA. This function is based on the work presented in several papers (see publications page). Arbitrary sensor geometries, channel measurement parameters, and sets of measurements can be set. http://www.eecs.umich.edu/~hero/localize/
