In the paper, an approach for project an optimal wireless sensor network indoors for the technology of the Internet of Things is proposed. To improve the energy efficiency of the network is used a hybrid network structure based on Wi-Fi and ZigBee standards. The advantage of the approach is that the network is designed on a three-dimensional model of the building, given the attenuation of the signal not only in the walls, but also in the floors. The combination of radio-wave (Motley-Keenan model) and optimization (genetic algorithm) methods for optimal arrangement of connecting and sensory nodes is used.
