Research on frequency hopping communication mechanism of WSN based on RSSI value

In the wireless sensor network applications, what is easily found that it is difficult to guarantee the quality of link communication in the communication channel by the scene frequency interference. In this paper, the frequency hopping communication mechanism of wireless sensor network based on RSSI is proposed. By analyzing the factors that affect the RSSI value, the RSSI value recognition network communication interference strategy is determined. By using the distributed decision fusion algorithm, all nodes participate in the network frequency hopping decision, effectively reduce the probability of false frequency decision error. The results show that the probability of accurate identification of interference is more than 95%, the error rate of FM decision can be controlled at 5%, and the quality of link communication is improved.
