Optimal Content Placement for Offloading in Cache-enabled Heterogeneous Wireless Networks
Dong Liu, Chenyang Yang
Caching at base stations (BSs) is a promising way to offload traffic and eliminate backhaul bottleneck in heterogeneous networks (HetNets). In this paper, we investigate the optima…
A Survey of Energy-Efficient Techniques for 5G Networks and Challenges Ahead
Stefano Buzzi, Chih-Lin I, Thierry E. Klein +3
After about a decade of intense research, spurred by both economic and operational considerations, and by environmental concerns, energy efficiency has now become a key pillar in t…
Energy-saving Pushing Based on Personal Interest and Context Information
Chuting Yao, Binqiang Chen, Chenyang Yang +1
Pushing files to users based on predicting the personal interest of each user may provide higher throughput gain than broadcasting popular files to users based on their common inte…
Cache-enabled Heterogeneous Cellular Networks: Comparison and Tradeoffs
Dong Liu, Chenyang Yang
Caching popular contents at base stations (BSs) is a promising way to unleash the potential of cellular heterogeneous networks (HetNets), where backhaul has become a bottleneck. In…
