摘要

The amount of transmitted information in wireless sensor networks usually needs to be limited due to the small size of sensors, limited energy capacity of their power supplies and other reasons. All this requires information processing and decision making directly in the sensors themselves. At the same time, the transmission of this information to the central node that makes the final decision can be carried out in different ways. It is usually believed that it is advisable to construct such a network using a star topology. However, this is not always possible. In this connection, in the paper two new approaches are proposed to the transmission and processing of information in sensors. For these two approaches, two optimal algorithms for information processing are synthesized, namely, the algorithms for complex detection of the observed object, and their efficiency is calculated. A comparison of the probabilities of the total error for these algorithms is performed depending on the number of sensors and the signal-to-noise ratio. The influence of the coordinates of the observed object on the efficiency of its detection is studied. The obtained results allow making a reasonable choice of the parameters of the wireless sensor network to solve the specified problem under the given conditions. #CSOC1120
