Abstract

In the actual wireless environment, the influence of shadow and fading will lead to different characteristics of the signals received by the sensor nodes. Therefore, some cooperative nodes in deep fading will have serious missed detection, which will affect the final result of fusion operation. To solve the above problems, this paper proposed a soft decision cooperative spectrum sensing method for cognitive wireless sensor network(CRSN) based on entropy weight method. The method organized the sensor nodes into logical groups to improve energy efficiency and sensing performance. After receiving the soft sensing information from all member nodes, the cluster head used the equal gain soft fusion to fuse among clusters, and then forwarded the local decision to the fusion center. In the final decision-making process, this paper used the entropy weight method to assign the optimal weight to the corresponding clustering local decision. Simulation results show that this method is superior to the typical cooperative spectrum sensing clustering scheme in terms of detection probability and total error probability.
