1. An indoor localization method for estimating the location of nodes, comprising the following steps: connecting at least one node to at least another node by at least two different types of channels, the first type of channel being configured to carry a first type of signal, the second type of channel being configured to carry a second type of signal different from the first type of signal, for each type of channel, determining a distance between the connected nodes based on data from said nodes and/or from said channel, for each type of channel, building a Euclidean Distance Matrix based on the determined distances, estimating the location of the nodes based on the built Euclidean Distance Matrices.
