The optimal node deployment of WSN based on security connection

To solve the problem of destroying the shared key between neighbor nodes caused by moving nodes in current sensor network coverage optimization scheme, this paper proposes a deployment scheme for Wireless Sensor Networks based on Voronoi centroid-based attractive virtual force and a security connection virtual force. Aiming at the optimal target of improving the nodes coverage, the proposed scheme adopts the security connection virtual force to ensure the safe connection of nodes, and aopts an improved Voronoi centroid-based attractive virtual force algorithm to effectively guide the node dispersal process and achieve global optimization. The simulation results prove that the proposed scheme can improve the coverage of sensor nodes and can reduce the damage of secure connections with shared keys among neighbor nodes.
