A Resource Scheduling Algorithm with Low Latency for 5G Networks Based on Effective Hybrid Genetic Algorithm and Tabu Search
A resource scheduling algorithm based on hybrid genetic algorithm and tabu search(named GATS)is proposed to solve the problem that the existing schedule methods are difficult to meet the requirement of the mobile communication with low latency. First
a dynamic bandwidth allocation policy of virtual links is established using an integer linear programming. Then
the transmission delay of data traffic in virtual links is introduced based on a traditional flexible job shop scheduling model
and the corresponding resource scheduling model for 5G is established. Owing to the complexity of the scheduling problem
the resource scheduling algorithm based on hybrid genetic algorithm and tabu search is developed for solving the problem efficiently. The algorithm introduces tabu search in optimization process of the genetic algorithm to balance capabilities of global and local searches
solves the problem of premature convergence of the genetic algorithm
and obtains better scheduling solutions. Simulation results show that the GATS algorithm outperforms the GA-BA algorithm in reducing the scheduling makespan by 17%
and caters to 5G service with stringent delay requirements
thereby increases users' experience and operators' revenues.
