Currently, the trend is to automate all the managements and control the maximum quantity of the environment information, like happens in the smart cities, in home automation or in the industry. To achieve this, the vest option is the use of wireless sensor networks (WSN) than include many little sensors. This sensors have to be able to send the information to a coordinator node, or even act if the situation requires. This sensors are nodes. In this Project, we use a development kit given by the company Nebusens© to design an indoor localization application, which objective to cover the maximum surface possible, and also be able to get the information of the environment of its nodes. The location system need fixed nodes, which we know the position, and we use this information as reference to obtain the position of the mobile nodes (tags), using the power or the delay and taking into account the indoor propagation modes. To cover the biggest surface possible, it pretends to establish different areas of localization where always a node will be connect two areas or more to forward the information to the coordinator. Will also analyze the kit, evaluating the performance, the Maneuverability, the sturdiness and how easy is use it.
