Abstract
Software-defined network provides a new implementation scheme for heterogeneous wireless network resource scheduling by separating control plane from data plane.Global resource scheduling algorithm based on SDN architecture,local resource scheduling algorithm and dynamic scheduling algorithm based on network state are researched and designed,and multi-layer heterogeneous network simulation environment is constructed for performance verification.The experimental results show that in the network congestion scenario,the response time of dynamic scheduling algorithm to the change of network state is reduced by 42%,the resource utilization efficiency is increased by 35%,and the dynamic scheduling algorithm has obvious advantages in the burst service processing.Multi-dimensional data analysis verifies the feasibility and advancement of this algorithm in SDN environment.关键词
