Location and power estimation of the radio transmitters is an efficient method of providing the radio environment maps in terms of database size and computation time. In this study, a novel efficient approach for estimating the power and location of active transmitters in the predefined geo-location is presented and the excellent results of this method are compared with other methods. Then, the raising question about number of required receiver sensors in the network area is discussed and an analytical relation is derived for this purpose. To perform experiment, the authors used distributed receivers in a site and conveyed their collected information about the received power in the specified bandwidth to the fusion centre. The results of this study are verified by both numerical simulations and experimental tests.
