Perhaps the most important part of building a radio environment map is estimating the electromagnetic field strength. The more efficient the estimation algorithm used, the more accurate the radio environment map reached. A new hybrid algorithm to estimate electromagnetic power - using sensing data gathered by monitoring sensors - is proposed in this paper. A certain propagation model was used considering all physical phenomena along the whole path of the electromagnetic wave (including losses, attenuation).A theoretical variogram based on a certain propagation model was used and fitted using a real variogram through regression. This method simulates the real physical phenomenon more accurately. The proposed algorithm is mainly based on weighting parameters (that rely on the variogram method) and a factor taking the similarities because of the neighborhood. Experimental results showed close similarity between given and computed electromagnetic power through regression curves and objective evaluation indices. The proposed method's main contribution is gathering the merits of using a suitable propagation model and a theoretical variogram, besides getting merits of traditional methods(like Inverse Distance Weight) using new vision.
