MODELING AND RESOURCE ALLOCATION IN MOBILE WIRELESS NETWORKS
… (IaaS), radios and radio resources in a wireless network can also be provisioned as a service to Mobile Virtual Network Operators (MVNOs), which we refer to as Radio-as-a-Service (RaaS). In this thesis, we present a novel auction-based model to enable fair pricing and fair resource …

Communications in Mobile Wireless Networks: A Finite Time-Horizon Viewpoint
In mobile wireless networks (MWNs), short-term communications carry two key features: 1) Different from communications over a large time window where the performance is governed by the long-term average effect, the short-term communications in MWNs are sensitive to the instantaneous location and …
