Aiming at the cooperation spectrum detection in Wireless Sensor Network(WSN),this paper presents a distributed spectrum detection based on sequential Markov chain.It assumes the detection of the single node is a Markov process,and the result value of local sequence detection is obtained by the Sequential Probability Ratio Test(SPRT).After the measurements result of each node's own is sent to the data fusion center,the final results can be determined in line with the threshold.Matlab simulation validates the sequential detection performance.
