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…
Dominant Resource Fairness in Cloud Computing Systems with Heterogeneous Servers
Wei Wang, Baochun Li, Ben Liang
We study the multi-resource allocation problem in cloud computing systems where the resource pool is constructed from a large number of heterogeneous servers, representing differen…
To Reserve or Not to Reserve: Optimal Online Multi-Instance Acquisition in IaaS Clouds
Wei Wang, Baochun Li, Ben Liang
Infrastructure-as-a-Service (IaaS) clouds offer diverse instance purchasing options. A user can either run instances on demand and pay only for what it uses, or it can prepay to re…
Optimal Frame Transmission for Scalable Video with Hierarchical Prediction Structure
Saied Mehdian, Ben Liang
An optimal frame transmission scheme is presented for streaming scalable video over a link with limited capacity. The objective is to select a transmission sequence of frames and t…
