Event-triggered Online Proactive Network Association to Mobile Edge Computing for IoT
Jian Zhang, Qimei Cui, Xuefei Zhang +2
Ultra-low latency communication for mobile machines emerges as a critical technology in Internet of Things (IoT). Proactive network association has been suggested to support ultra-…
Distributed Layered Grant-Free Non-Orthogonal Multiple Access for Massive MTC
Hui Jiang, Qimei Cui, Yu Gu +3
Grant-free transmission is considered as a promising technology to support sporadic data transmission in massive machine-type communications (mMTC). Due to the distributed manner,…
User Association for Offloading in Heterogeneous Network Based on Matern Cluster Process
Yuxuan Xie, Xuefei Zhang, Qimei Cui +1
Future mobile networks are converging toward heterogeneous multi-tier networks, where various classes of base stations (BS) are deployed based on user demand. So it is quite necess…
Preserving Reliability to Heterogeneous Ultra-Dense Distributed Networks in Unlicensed Spectrum
Qimei Cui, Yu Gu, Wei Ni +4
This article investigates the prominent dilemma between capacity and reliability in heterogeneous ultra-dense distributed networks, and advocates a new measure of effective capacit…
