Abstract
In this work, the synthesis and analysis of the algorithm that makes a decision on the presence or absence of the observed object using the spatially distributed sensors of wireless sensor networks are executed. The peculiarities of the influence of the external environment on the functioning of local sensors on the example of sound and vibration sensors are shown. With the purpose of determine the degree of influence of the environment on the efficiency of functioning of the system, theoretical formulas for the decision-making efficiency indicators are obtained. The dependences of the total error probability on the energy parameter taking into account the attenuation in the environment are presented. The main types of propagation environment were considered. Analysis of the results is executed and the degree of influence of the environment on the quality of functioning of the wireless sensor system is evaluated. Herewith it was shown that its efficiency, despite its possible significant deterioration due to strong absorption by the propagation environment, can be increased on account of increasing the number of sensors used.
