Analysis and Optimization of Age of Information in Large-Scale Random Access Networks
Yueqi Chen, Siqi Fan, Zhuoyi Zhao +2
We consider a large-scale network where multiple nodes transmit time-sensitive information via a shared channel to a wireless base station using a Carrier-Sense Multiple Access (CS…
What Is the Cost of a Handover Interruption? Rethinking 5G Mobility for Aerial Vehicles
André Melo, Yueqi Chen, Igor Kadota +1
Low-altitude aviation is moving toward large-scale operations increasingly dependent on 5G cellular connectivity. However, 5G mobility remains blind to the operational risk of its…
Who Can Safely Wait? Risk-Aware 5G Scheduling for Low-Altitude UAV Operation
André Melo, Yueqi Chen, Lourenço Pereira +1
Cellular-connected UAV operations already fly in many countries. However, cellular networks were designed for terrestrial users and remain blind to the operational consequences of…
Toward Practical Age-of-Information Scheduling in 5G Cellular
Zhuoyi Zhao, Igor Kadota
We consider a 5G cellular network where a gNB schedules time-sensitive uplink transmissions from multiple UEs and forwards received packets to remote destinations. In practical 5G…
Optimizing Age of Information without Knowing the Age of Information
Zhuoyi Zhao, Igor Kadota
Consider a network where a wireless base station (BS) connects multiple source-destination pairs. Packets from each source are generated according to a renewal process and are enqu…
WiSwarm: Age-of-Information-based Wireless Networking for Collaborative Teams of UAVs
Vishrant Tripathi, Igor Kadota, Ezra Tal +4
The Age-of-Information (AoI) metric has been widely studied in the theoretical communication networks and queuing systems literature. However, experimental evaluation of its applic…
Switching in the Rain: Predictive Wireless x-haul Network Reconfiguration
Igor Kadota, Dror Jacoby, Hagit Messer +2
Wireless x-haul networks rely on microwave and millimeter-wave links between 4G and/or 5G base-stations to support ultra-high data rate and ultra-low latency. A major challenge ass…
WiFresh: Age-of-Information from Theory to Implementation
Igor Kadota, Muhammad Shahir Rahman, Eytan Modiano
Emerging applications, such as smart factories and fleets of drones, increasingly rely on sharing time-sensitive information for monitoring and control. In such application domains…
Minimizing the Age of Information in Wireless Networks with Stochastic Arrivals
Igor Kadota, Eytan Modiano
We consider a wireless network with a base station serving multiple traffic streams to different destinations. Packets from each stream arrive to the base station according to a st…
Scheduling Policies for Age Minimization in Wireless Networks with Unknown Channel State
Rajat Talak, Igor Kadota, Sertac Karaman +1
Age of information (AoI) is a recently proposed metric that measures the time elapsed since the generation of the last received information update. We consider the problem of AoI m…
Scheduling Policies for Minimizing Age of Information in Broadcast Wireless Networks
Igor Kadota, Abhishek Sinha, Elif Uysal-Biyikoglu +2
We consider a wireless broadcast network with a base station sending time-sensitive information to a number of clients through unreliable channels. The Age of Information (AoI), na…
