1. A method of calibrating an indoor space for localizing a mobile device, the method comprising:
obtaining, by a processor, sensorial data for a zone in the indoor space, the zone being associated with a set of factors influencing a behavior of the sensorial data in the zone, the set of factor comprising at least one of a size of the zone, a shape of the zone, a type of the zone, a number of users passing through the one, and predicted movement patterns of a mobile device in the zone;
estimating, by the processor, at least one component of instantaneous localization in the zone based on the sensorial data, wherein the estimating comprises simulating variation of the at least one component owing to behavior of the sensorial data in the zone;
evaluating, by the processor, the estimation of the at least one component based on a ground truth value of the at least one component;
associating, by the processor, a localization criterion with the zone, wherein the localization criterion is indicative of a selectivity in use of the sensorial data for localizing the mobile device in the zone, the localization criterion being based on the evaluating; and
providing, by the processor, indoor-location based services to mobile devices in the indoor space using the localization criterion, wherein the mobile devices are to perform localization based on the localization criterion.
