Understanding Age of Information in Large-Scale Wireless Networks
Howard H. Yang, Chao Xu, Xijun Wang +2
The notion of age-of-information (AoI) is investigated in the context of large-scale wireless networks, in which transmitters need to send a sequence of information packets, which…
Performance Analysis for Multi-Antenna Small Cell Networks with Clustered Dynamic TDD
Hongguang Sun, Howard H. Yang, Xijun Wang +2
Small cell networks with dynamic time-division duplex (D-TDD) have emerged as a potential solution to address the asymmetric traffic demands in 5G wireless networks. By allowing th…
Deep Reinforcement Learning for Fresh Data Collection in UAV-assisted IoT Networks
Mengjie Yi, Xijun Wang, Juan Liu +2
Due to the flexibility and low operational cost, dispatching unmanned aerial vehicles (UAVs) to collect information from distributed sensors is expected to be a promising solution…
Average Age of Changed Information in the Internet of Things
Wenrui Lin, Xijun Wang, Chao Xu +2
The freshness of status updates is imperative in mission-critical Internet of things (IoT) applications. Recently, Age of Information (AoI) has been proposed to measure the freshne…
AoI and Energy Consumption Oriented Dynamic Status Updating in Caching Enabled IoT Networks
Chao Xu, Xijun Wang, Howard H. Yang +2
