Cooperative full duplex content sensing and delivery improves the offloading probability of D2D caching

Cooperative full duplex content sensing and delivery improves the offloading probability of D2D caching
A novel policy is conceived for device-to-device (D2D) caching that facilitates content sensing and delivery using full duplex (FD) communications. As a benefit, the user devices become capable of performing content sensing and delivery over an extended geographic range, where more aggregate cache units are available, hence circumventing both the limited communication range and the limited storage of individual devices. Based on a stochastic geometry aided modeling of the network, we analytically derive the hit ratio, defined as the probability that a content requester (CR) can obtain desired file via a D2D
link or an FD D2D link with data rate larger than a given threshold. The accuracy of our analysis is validated by our Monte Carlo simulations. Our numerical results show that the proposed policy achieves higher offloading probability than that of the existing approaches, even in the face of limited self-interference cancellation capability.

Abstract

A novel policy is conceived for device-to-device (D2D) caching that facilitates content sensing and delivery using full duplex (FD) communications. As a benefit, the user devices become capable of performing content sensing and delivery over an extended geographic range, where more aggregate cache units are available, hence circumventing both the limited communication range and the limited storage of individual devices. Based on a stochastic geometry aided modeling of the network, we analytically derive the hit ratio, defined as the probability that a content requester (CR) can obtain desired file via a D2D
link or an FD D2D link with data rate larger than a given threshold. The accuracy of our analysis is validated by our Monte Carlo simulations. Our numerical results show that the proposed policy achieves higher offloading probability than that of the existing approaches, even in the face of limited self-interference cancellation capability.
