Optimal Caching Placement for D2D Assisted Wireless Caching Networks
Jun Rao, Hao Feng, Chenchen Yang +2
In this paper, we devise the optimal caching placement to maximize the offloading probability for a two-tier wireless caching system, where the helpers and a part of users have cac…
When ICN Meets C-RAN for HetNets: An SDN Approach
Chenchen Yang, Zhiyong Chen, Bin Xia +1
In this paper, we contribute to novelly proposing and elaborating the integration of the ICN, C-RAN and SDN for the HetNet to achieve win-win situation. The vision of the proposed…
Modeling and Analysis for Cache-enabled Cognitive D2D Communications in Cellular Networks
Chenchen Yang, Xingya Zhao, Yao Yao +1
Exploiting cognition to the cache-enabled device-to-device (D2D) communication underlaying the multi-channel cellular network is the main focus of this paper. D2D pairs perform dir…
Analysis on Cache-enabled Wireless Heterogeneous Networks
