Pricing Mechanisms for Crowd-Sensed Spatial-Statistics-Based Radio Mapping
Xuhang Ying, Sumit Roy, Radha Poovendran
Networking on white spaces (i.e., locally unused spectrum) relies on active monitoring of spectrum usage. Spectrum databases based on empirical radio propagation models are widely…
Performance Analysis of CSMA with Multi-Packet Reception: The Inhomogeneous Case
Shwan Ashrafi, Chen Feng, Sumit Roy
The problem of Carrier Sense Multiple Access (CSMA) with multi-packet reception (MPR) is studied. Most prior work has focused on the homogeneous case, where all the mobile users ar…
A Modified CSMA/CA Protocol for OFDM Underwater Networks: Cross Layer Design
Yanling Yin, Sumit Roy, Payman Arabshahi
The underwater acoustic channel continues to present significant challenges to efficient throughput performance of underwater acoustic sensor networks (UASNs) in varying scenarios.…
PCF Scheme for Periodic Data Transmission in Smart Metering Network with Cognitive Radio
Yue Yang, Sumit Roy
The next generation Advanced Metering Infrastructure (AMI), with the aid of two-way Smart Metering Network (SMN), is expected to support many advanced functions. In this work, we f…
Spectrum Sharing Between A Surveillance Radar and Secondary Wi-Fi Networks
Farzad Hessar, Sumit Roy
Co-existence between unlicensed networks that share spectrum spatio-temporally with terrestrial (e.g. Air Traffic Control) and shipborne radars in 3-GHz band is attracting signific…
