Cooperative Data Collection with Multiple UAVs for Information Freshness in the Internet of Things
Xijun Wang, Mengjie Yi, Juan Liu +3
Maintaining the freshness of information in the Internet of Things (IoT) is a critical yet challenging problem. In this paper, we study cooperative data collection using multiple U…
Age of Changed Information: Content-Aware Status Updating in the Internet of Things
Xijun Wang, Wenrui Lin, Chao Xu +2
In Internet of Things (IoT), the freshness of status updates is crucial for mission-critical applications. In this regard, it is suggested to quantify the freshness of updates by u…
When to Preprocess? Keeping Information Fresh for Computing Enable Internet of Things
Xijun Wang, Minghao Fang, Chao Xu +4
Age of information (AoI), a notion that measures the information freshness, is an essential performance measure for time-critical applications in Internet of Things (IoT). With the…
Optimizing Age of Information in Random-Access Poisson Networks
Xinghua Sun, Fangming Zhao, Howard H. Yang +3
Timeliness is an emerging requirement for many Internet of Things (IoT) applications. In IoT networks, where a large-number of nodes are distributed, severe interference may incur…
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…
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…
