Gateway device optimal deployment method for smart highway system

Abstract

The invention discloses a method for optimizing the deployment of gateway equipment used in a smart road system, which mainly solves the problems of low network reliability and operating efficiency caused by unreasonable deployment of gateway equipment in the system. The solution is: build a gateway device deployment optimization model based on the number of gateways, gateway load balancing and data transmission costs; initialize the alternative deployment locations of the gateway equipment; select several locations in the alternative deployment locations as the actual deployment locations of the gateway equipment , to form a deployment scheme for gateway equipment; execute the loop multiple times to form a gateway equipment deployment scheme set E composed of multiple equipment deployment schemes; construct a fitness function according to the optimization goal, and use the fitness function value as an optimization index to optimize the equipment The deployment plan set E performs iterative optimization and plan update to obtain the optimal deployment plan of the gateway device. The invention improves the stability, reliability and operation efficiency of the system network, and can be used in the informatization and network construction of the intelligent highway system.
