Zhiwen Hu, Zijie Zheng, Tao Wang, Lingyang Song, Xiaoming Li

TL;DR
This paper introduces a novel caching-as-a-service framework for small-cell networks, utilizing auction mechanisms to allocate storage among competing service providers, enhancing network flexibility and performance.
Contribution
It proposes a multi-object auction-based mechanism for content caching among multiple service providers in small-cell networks, considering dynamic system parameters and content replacement frequency.
Findings
Auction-based caching improves resource allocation efficiency.
Simulation demonstrates satisfactory performance of the proposed mechanism.
Enhances flexibility and performance in wireless network virtualization.
Abstract
Wireless network virtualization has been well recognized as a way to improve the flexibility of wireless networks by decoupling the functionality of the system and implementing infrastructure and spectrum as services. Recent studies have shown that caching provides a better performance to serve the content requests from mobile users. In this paper, we propose that \emph{caching can be applied as a service} in mobile networks, i.e., different service providers (SPs) cache their contents in the storages of wireless facilities that owned by mobile network operators (MNOs). Specifically, we focus on the scenario of \emph{small-cell networks}, where cache-enabled small-cell base stations (SBSs) are the facilities to cache contents. To deal with the competition for storages among multiple SPs, we design a mechanism based on multi-object auctions, where the time-dependent feature of system…
