Edge Computing Aware NOMA for 5G Networks
Abbas Kiani, Nirwan Ansari
With the fast development of Internet of things (IoT), the fifth generation (5G) wireless networks need to provide massive connectivity of IoT devices and meet the demand for low l…
Energy-Aware Virtual Machine Management in Inter-datacenter Networks over Elastic Optical Infrastructure
Liang Zhang, Tao Han, Nirwan Ansari
Datacenters (DCs), deployed in a large scale to support the ever increasing demand for data processing applications, consume tremendous energy. Powering DCs with renewable energy c…
Mobile Edge Computing Empowers Internet of Things
Nirwan Ansari, Xiang Sun
In this paper, we propose a Mobile Edge Internet of Things (MEIoT) architecture by leveraging the fiber-wireless access technology, the cloudlet concept, and the software defined n…
Latency Aware Drone Base Station Placement in Heterogeneous Networks
Xiang Sun, Nirwan Ansari
Different from traditional static small cells, Drone Base Stations (DBSs) exhibit their own advantages, i.e., faster and cheaper to deploy, more flexibly reconfigured, and likely t…
Joint Spectrum Allocation and Structure Optimization in Green Powered Heterogeneous Cognitive Radio Networks
Ali Shahini, Nirwan Ansari
We aim at maximizing the sum rate of secondary users (SUs) in OFDM-based Heterogeneous Cognitive Radio (CR) Networks using RF energy harvesting. Assuming SUs operate in a time swit…
Indoor Localization by Fusing a Group of Fingerprints Based on Random Forests
Xiansheng Guo, Nirwan Ansari, Huiyong Li
Indoor localization based on SIngle Of Fingerprint (SIOF) is rather susceptible to the changing environment, multipath, and non-line-of-sight (NLOS) propagation. Building SIOF is a…
