摘要
针对无线系统中基站负载不均衡问题,提出一种利用Python+Keras框架测试CNN模型的负载均衡方案,首先提出考虑基站的负载的优化问题,通过基于图论的库恩-马克(Kuhn-Munkres,KM)算法求解,并设计训练了CNN网络模型来学习信道状态信息到实现负载均衡的解之间的非线性映射关系。实验仿真表明,该网络模型可以自动提取信道状态信息的特征并激活链路,准确率达到98.6%,不仅取得了基站间更均衡的负载,计算复杂度也更低,实现了快速可靠的关联调度。
Aiming at the problem of base station load imbalance in wireless systems,a user association scheme using Python+Keras framework to test CNN is proposed.First,the load of the base station is considered in the optimization problem,solved by the Kuhn-Munkres(KM)algorithm based on graph theory,and a user association algorithm based on CNN is designed and trained.Multiple sets of experimental simulations show that the network model can automatically extract the characteristics of the channel state information between the base station and the user and activate the link,with an accuracy rate of 98.6%.Not only a more balanced load between the base stations is achieved,but also computational complexity is lower,fast and reliable associated scheduling is realized.
