Abstract

With the ever-increasing service requirements of wireless networks, the spectrum resources of the cellular architecture are limited, and the backhaul capacity will become a system bottleneck. In order to alleviate this bottleneck, this paper considered a special heterogeneous cellular network, combined with the deployment of cache nodes, user location distribution, and considers user preferences for content requests and the limited storage space of cache nodes, modeling and analysis of the joint optimization problem of content storage and user association. And it modeled the objective function as the minimization of request delay. It simply proves that the problem is NP-hard, and designed a content placement strategy based on improved Kuhn-Munkres. Finally, the performance of this algorithm was compared with other benchmark schemes through experi-ments.
