Research on spectrum sensing algorithm of coal mine based on Strackelberg game theory

Abstract

In view of problem of low accuracy of spectrum sensing technology of coal mine, a spectrum sensing algorithm of coal mine based on Strackelberg game theory was proposed. The algorithm divides cognitive nodes into leading nodes and following nodes according to good or poor sensing performance of cognitive nodes, and following nodes with poor sensing performance take the decision of leading nodes which have good sensing performance. The Matlab simulation results show that the algorithm improves spectrum sensing performance of coal mine.
