Optimal Distribution Design for Irregular Repetition Slotted ALOHA with Multi-Packet Reception
Zhengchuan Chen, Yifan Feng, Chundie Feng +3
Associated with multi-packet reception at the access point, irregular repetition slotted ALOHA (IRSA) holds a great potential in improving the access capacity of massive machine ty…
Age-optimal Service and Decision Scheduling in Internet of Things
Zhiwei Bao, Yunquan Dong, Zhengchuan Chen +2
We consider an Internet of Things (IoT) system in which a sensor observes a phenomena of interest with exponentially distributed intervals and delivers the updates to a monitor wit…
Age-upon-Decisions Minimizing Scheduling in Internet of Things: To be Random or to be Deterministic?
Yunquan Dong, Zhengchuan Chen, Shanyun Liu +2
We consider an Internet of Things (IoT) system in which a sensor delivers updates to a monitor with exponential service time and first-come-first-served (FCFS) discipline. We inves…
Age of Information Upon Decisions
Yunquan Dong, Zhengchuan Chen, Shanyun Liu +1
We consider an M/M/1 update-and-decide system where Poisson distributed decisions are made based on the received updates. We propose to characterize the freshness of the received u…
Improving Network Availability of Ultra-Reliable and Low-Latency Communications with Multi-Connectivity
Changyang She, Zhengchuan Chen, Chenyang Yang +3
Ultra-reliable and low-latency communications (URLLC) have stringent requirements on quality-of-service and network availability. Due to path loss and shadowing, it is very challen…
Beyond Empirical Models: Pattern Formation Driven Placement of UAV Base Stations
Jiaxun Lu, Shuo Wan, Xuhong Chen +3
This work considers the placement of unmanned aerial vehicle base stations (UAV-BSs) with criterion of minimum UAV-recall-frequency (UAV-RF), indicating the energy efficiency of mo…
