Abstract:

While Wireless Sensor Network（WSN） realizes the interconnection of everything, the security of wireless communication is facing challenges. WSN network nodes are deployed randomly, and the network structure changes dynamically, making the existing secure communication schemes unable to be directly applied. In order to solve this problem, this paper uses random Poisson point process to model the location of network nodes, and uses random geometric tools to analyze the physical layer security performance of wireless sensor network system, with the probability of security interruption and connection interruption as indicators. The simulation verifies the correctness of the theoretical analysis. The simulation results show that the security and reliability of the system can be optimized by arranging the sensor node density reasonably.
