The wireless sensor networks communication channels analytical models are proposed. They are provided in the form of the bit error rate dependences in case of the incoherent reception of messages from the energy and stochastic parameters of the information distorted signal and additive interference at the receiver input. Formula expressions for the probability of bit error are obtained for cases: fading signal and unfading interference; independent signal fading and Rayleigh interference. Complex indices to account energy interaction of the reference signal are substantiated. The signal is formed by the demodulator in the receiver, with the additive interference and the distorted signal at the communication channel output. The impact of a indices value changes on the authenticity of the messages transfer in the communication channel is investigated, for example, with regard to the rejection of additive interference.
