Research of wireless sensor network key distribution mechanism based on Internet of Things

Abstract

According to the sensor network in the topology structure of Internet of Things, the sensor network was divided by hexagon method to optimize network random key pre-distribution protocol to improve the safety of Things. The optimal performance of sensor networks can be obtained, which is divided by the fitted respectively, after sub-network connectivity and the node with the key anti-capture the relationship between the distribution images was shown by the experimental data. Experiments show that the scheme has a better key connectivity and capture of anti-nodes.
