How to Discover Knowledge for FutureG: Contextual RAG and LLM Prompting for O-RAN
Nathan Conger, Nathan Scollar, Kemal Davaslioglu +2
We present a retrieval-augmented question answering framework for 5G/6G networks, where the Open Radio Access Network (O-RAN) has become central to disaggregated, virtualized, and…
Coordinated Anti-Jamming Resilience in Swarm Networks via Multi-Agent Reinforcement Learning
Bahman Abolhassani, Tugba Erpek, Kemal Davaslioglu +2
Reactive jammers pose a severe security threat to robotic-swarm networks by selectively disrupting inter-agent communications and undermining formation integrity and mission succes…
Targeted Attacks and Defenses for Distributed Federated Learning in Vehicular Networks
Utku Demir, Tugba Erpek, Yalin E. Sagduyu +2
In emerging networked systems, mobile edge devices such as ground vehicles and unmanned aerial system (UAS) swarms collectively aggregate vast amounts of data to make machine learn…
MULTI-SCOUT: Multistatic Integrated Sensing and Communications in 5G and Beyond for Moving Target Detection, Positioning, and Tracking
Yalin E. Sagduyu, Kemal Davaslioglu, Tugba Erpek +3
This paper presents a complete signal-processing chain for multistatic integrated sensing and communications (ISAC) using 5G Positioning Reference Signal (PRS). We consider a distr…
Relay Selection and User Equipment Admission in Resource-Efficient NextG Sidelink Communications
Yalin E. Sagduyu, Tugba Erpek, Sastry Kompella +1
5G/6G sidelink communications addresses the challenge of connecting outer UEs, which are unable to directly access a base station (gNodeB), through inner UEs that act as relays to…
Distributed Federated Learning for Vehicular Network Security: Anomaly Detection Benefits and Multi-Domain Attack Threats
Utku Demir, Yalin E. Sagduyu, Tugba Erpek +3
In connected and autonomous vehicles, machine learning for safety message classification has become critical for detecting malicious or anomalous behavior. However, conventional ap…
AoI, Timely-Throughput, and Beyond: A Theory of Second-Order Wireless Network Optimization
Daojing Guo, Khaled Nakhleh, I-Hong Hou +2
This paper introduces a new theoretical framework for optimizing second-order behaviors of wireless networks. Unlike existing techniques for network utility maximization, which onl…
Age Optimum Sampling in Non-Stationary Environment
Jinheng Zhang, Haoyue Tang, Jintao Wang +2
In this work, we consider a status update system with a sensor and a receiver. The status update information is sampled by the sensor and then forwarded to the receiver through a c…
Age-Optimal Multi-Flow Status Updating with Errors: A Sample-Path Approach
Yin Sun, Sastry Kompella
In this paper, we study an age of information minimization problem in continuous-time and discrete-time status updating systems that involve multiple packet flows, multiple servers…
A Theory of Second-Order Wireless Network Optimization and Its Application on AoI
Daojing Guo, Khaled Nakhleh, I-Hong Hou +2
This paper introduces a new theoretical framework for optimizing second-order behaviors of wireless networks. Unlike existing techniques for network utility maximization, which onl…
Learning the Optimal Synchronization Rates in Distributed SDN Control Architectures
Konstantinos Poularakis, Qiaofeng Qin, Liang Ma +3
Since the early development of Software-Defined Network (SDN) technology, researchers have been concerned with the idea of physical distribution of the control plane to address sca…
Coexistence of Radar and Communication Systems in CBRS Bands Through Downlink Power Control
Neelakantan Nurani Krishnan, Ratnesh Kumbhkar, Narayan B. Mandayam +2
Citizen Broadband Radio Service band (3550 - 3700 GHz) is seen as one of the key frequency bands to enable improvements in performance of wireless broadband and cellular systems. A…
How Close Can I Be? - A Comprehensive Analysis of Cellular Interference on ATC Radar
Neelakantan Nurani Krishnan, Ratnesh Kumbhkar, Narayan B. Mandayam +2
Increasing data traffic demands over wireless spectrum have necessitated spectrum sharing and coexistence between heterogeneous systems such as radar and cellular communications sy…
Power Optimal Non-contiguous Spectrum Access in Multi Front End Radio Enabled Point-to-Point Link
Muhammad Nazmul Islam, Narayan B. Mandayam, Sastry Kompella +1
Non-contiguous spectrum chunks allow wireless links to flexibly access a wide amount of bandwidth. Multi- Channel Multi-Radio (MC-MR) and Non-Contiguous Orthogonal Frequency Divisi…
System Power Minimization to Access Non-Contiguous Spectrum in Cognitive Radio Networks
Muhammad Nazmul Islam, Narayan B. Mandayam, Sastry Kompella +1
Wireless transmission using non-contiguous chunks of spectrum is becoming increasingly important due to a variety of scenarios such as: secondary users avoiding incumbent users in…
