A reliability-based distributed security control method for a wireless sensor network relates to the technical field of wireless communication. The present invention solves the problems that existing network security control methods cannot realize system security control under complex network attacks and have poor universality. In an ideal state, the present invention establishes a model of each sensor node in a wireless sensor network, uses the node model to design a distributed controller; uses the distributed controller to solve the gain of the distributed controller; uses the distributed controller Gain evaluates the credibility of the received data of adjacent wireless sensor nodes, and calculates the weight of the credibility; uses the weight of the credibility to establish an adaptive isolation mechanism, and uses the adaptive isolation mechanism to update the state of the sensor node ; Realize security control strategy update. The invention is applicable to the security control of the wireless sensor network.
Description
technical field [0001] The present invention relates to the technical field of wireless communication. Background technique [0002] Wireless sensor network is a distributed network composed of a large number of sensor nodes in a self-organized and multi-hop manner. With its unique advantages such as convenient deployment, strong mobility, and low cost, it is widely used in intelligent transportation, environmental detection, medical and health and many other fields. favored. However, with the increasing application of wireless sensor networks, the security control of network systems has become a hot topic in current research. Since the wireless sensor nodes transmit data through the wireless communication link, it is of great significance to study the reliability of the communication link to realize the safe and accurate control of the system. [0003] In view of the possible network attacks on the communication chain of sensor nodes, many scholars at home and abroad have...
