1. A system for localizing an object in an indoor environment, the system comprising:
a wireless communication infrastructure, configured to enable wireless communication inside the indoor environment via a wireless communication network, the wireless communication infrastructure comprising:
a plurality of wireless access points, configured to provide mobile network devices with access to the wireless communication network;
at least one cooperative mobile network device in communication with at least one of the plurality of wireless access points; and
a processing device;
wherein each of the wireless access points is configured to sense first signal propagation data of wireless signals transmitted via the wireless communication network;
wherein the cooperative mobile network device is configured to sense second signal propagation data of wireless signals transmitted via the wireless communication network;
wherein the cooperative mobile network device is configured to evaluate the second signal propagation data and to determine its own position based on the evaluated second signal propagation data and positions of the wireless access points; and
wherein the processing device is configured to evaluate the first signal propagation data and to extract localization data indicative of the position of an object located in the indoor environment based on the evaluated first signal propagation data, on the evaluated second signal propagation data, on the determined position of the cooperative mobile network device, and on the positions of the wireless access points.
