Abstract:

To solve the wireless backhaul problem in 5G dynamic heterogeneous scenarios, a wireless backhaul optimization algorithm considering delay jitter is proposed. Firstly, the problem of delay and delay jitter in 5G dynamic heterogeneous scenarios is systematically analyzed, and an optimization index is established. Then, a basic backhaul model is constructed. On this basis, considering delay optimization requirements, improved model 1 is constructed by adding delay constraints; considering network overload situations, improved model 2 is constructed by relaxing channel number allocation variables. Then, the corresponding hierarchical algorithms are proposed to quickly solve the above models. Simulation results show that the proposed algorithm has better delay jitter performance than three existing wireless backhaul optimization algorithms.
