Analysis of the effect of interference on the effectiveness of the detection of an object in wireless sensory networks with sound sensors and vibration

Background. The absorption of radiation from an object in the environment has a great influence on the efficiency of wireless sensor networks. Taking into account also the need to transmit information from sensors to a central point delivering a final (complex) solution, it should be noted that the task of detecting a radiation object (target) in such systems depends significantly on the terrain. Indeed, often the direct transmission of information from sensors to the central node is not possible, and therefore the information has to be transmitted sequentially from sensor to sensor. Aim. Develop target detection algorithms used both in the sensors themselves and in the central node, with a consistent transmission of information from sensor to sensor taking into account the attenuation of radiation from the object when using sound and vibration type sensors. Methods. The synthesis of reception algorithms was carried out by classical methods of statistical processing of information, and the analysis of efficiency was carried out according to obtained exact recurrency formulas. Results. Two complex algorithms of object detection in wireless sensor networks were synthesized and their efficiency was determined for two types of sensors and different radiation propagation media. The former is shown to be more efficient than the latter, but loses out on the second algorithm due to the need to use sensors with higher power consumption. Conclusion. The results obtained during the studies can be effectively used in selecting the type of sensors depending on the characteristics of the propagation environment and the interference situation.
