Flow-Packet Hybrid Traffic Classification for Class-Aware Network Routing
Sayantan Chowdhury, Ben Liang, Ali Tizghadam +1
Network traffic classification using machine learning techniques has been widely studied. Most existing schemes classify entire traffic flows, but there are major limitations to th…
Software Defined Networking Enabled Wireless Network Virtualization: Challenges and Solutions
Ning Zhang, Peng Yang, Shan Zhang +5
Next generation (5G) wireless networks are expected to support the massive data and accommodate a wide range of services/use cases with distinct requirements in a cost-effective, f…
Optimizing User Association and Spectrum Allocation in HetNets: A Utility Perspective
Yicheng Lin, Wei Bao, Wei Yu +1
The joint user association and spectrum allocation problem is studied for multi-tier heterogeneous networks (HetNets) in both downlink and uplink in the interference-limited regime…
Uplink Interference Analysis for Two-tier Cellular Networks with Diverse Users under Random Spatial Patterns
Wei Bao, Ben Liang
Multi-tier architecture improves the spatial reuse of radio spectrum in cellular networks, but it introduces complicated heterogeneity in the spatial distribution of transmitters,…
Structured Spectrum Allocation and User Association in Heterogeneous Cellular Networks
Wei Bao, Ben Liang
We study joint spectrum allocation and user association in heterogeneous cellular networks with multiple tiers of base stations. A stochastic geometric approach is applied as the b…
Understanding the Benefits of Open Access in Femtocell Networks: Stochastic Geometric Analysis in the Uplink
Wei Bao, Ben Liang
We introduce a comprehensive analytical framework to compare between open access and closed access in two-tier femtocell networks, with regard to uplink interference and outage. In…
Insensitivity of User Distribution in Multicell Networks under General Mobility and Session Patterns
Wei Bao, Ben Liang
The location of active users is an important factor in the performance analysis of mobile multicell networks, but it is difficult to quantify due to the wide variety of user mobili…
On Stability Region and Delay Performance of Linear-Memory Randomized Scheduling for Time-Varying Networks
Mahdi Lotfinezhad, Ben Liang, Elvino S. Sousa
Throughput optimal scheduling policies in general require the solution of a complex and often NP-hard optimization problem. Related literature has shown that in the context of time…
Joint Cooperation and Multi-Hopping Increase the Capacity of Wireless Networks
Sam Vakil, Ben Liang
The problem of communication among nodes in an \emph{extended network} is considered, where radio power decay and interference are limiting factors. It has been shown previously th…
