Blockchain for Data Sharing at the Network Edge: Trade-Off Between Capability and Security
Yixin Li, Liang Liang, Yunjian Jia +3
Blokchain is a promising technology to enable distributed and reliable data sharing at the network edge. The high security in blockchain is undoubtedly a critical factor for the ne…
Violation Probabilities of AoI and PAoI and Optimal Arrival Rate Allocation for the IoT-based Multi-Source Status Update System
Tianci Zhang, Shutong Chen, Zhengchuan Chen +4
Lots of real-time applications over Internet of things (IoT)-based status update systems have imperative demands on information freshness, which is usually evaluated by age of info…
Analysis of Age of Information in Dual Updating Systems
Zhengchuan Chen, Dapeng Deng, Howard H. Yang +5
We study the average Age of Information (AoI) and peak AoI (PAoI) of a dual-queue status update system that monitors a common stochastic process. Although the double queue parallel…
Age of Information: A Two-Sensor Status Update System Monitoring The Same Process
Tianqing Yang, Zhengchuan Chen, Howard H. Yang +3
This work studies the average age of information (AoI) of a monitoring system in which two sensors are sensing the same physical process and update status to a common monitor using…
Minimizing Age-upon-Decisions in Bufferless System: Service Scheduling and Decision Interval
Shutong Chen, Tianci Zhang, Zhengchuan Chen +4
In Internet of Things (IoT), the decision timeliness of time-sensitive applications is jointly affected by the statistics of update process and decision process. This work consider…
Reconfigurable Intelligent Surface-Aided Spectrum Sharing Coexisting with Multiple Primary Networks
Zhong Tian, Zhengchuan Chen, Min Wang +2
Considering the spectrum sharing system (SSS) coexisting with multiple primary networks, we have employed a well-designed reconfigurable intelligent surface (RIS) to control the ra…
