Enhanced VIP Algorithms for Forwarding, Caching, and Congestion Control in Named Data Networks
Ying Cui, Fan Lai, Edmund Yeh +1
Emerging Information-Centric Networking (ICN) architectures seek to optimally utilize both bandwidth and storage for efficient content distribution over the network. The Virtual In…
Distributed Stochastic Optimization for Weakly Coupled Systems with Applications to Wireless Communications
Fan Zhang, Ying Cui, Vincent K. N. Lau +1
In this paper, a framework is proposed to simplify solving the infinite horizon average cost problem for the weakly coupled multi-dimensional systems. Specifically, to address the…
Optimal Caching and User Association in Cache-enabled Heterogeneous Wireless Networks
Ying Cui, Fan Lai, Stephen Hanly +1
Heterogenous wireless networks (Hetnets) provide a powerful approach to meet the massive growth in traffic demands, but also impose a significant challenge on backhaul. Caching at…
Analysis and Optimization of Caching and Multicasting in Large-Scale Cache-Enabled Heterogeneous Wireless Networks
Ying Cui, Dongdong Jiang
Heterogeneous wireless networks (HetNets) provide a powerful approach to meet the dramatic mobile traffic growth, but also impose a significant challenge on backhaul. Caching and m…
User-Centric Interference Nulling in Downlink Multi-Antenna Heterogeneous Networks
Yueping Wu, Ying Cui, Bruno Clerckx
Heterogeneous networks (HetNets) have strong interference due to spectrum reuse. This affects the signal-to-interference ratio (SIR) of each user, and hence is one of the limiting…
Optimization-Based Linear Network Coding for General Connections of Continuous Flows
Ying Cui, Muriel Médard, Edmund Yeh +2
For general connections, the problem of finding network codes and optimizing resources for those codes is intrinsically difficult and little is known about its complexity. Most of…
