End-to-End Delay Approximation in Packet-Switched Networks
Yu Chen
In this paper, I develop a generalized method to approximate end-to-end delay (average delay, jitter and density functions) in packet-switched networks (PSNs) of any size under 1)…
Accurate Energy-Efficient Power Control for Uplink NOMA Systems under Delay Constraint
Bowen Cai, Yu Chen, Qimei Cui +2
Machine-type communications (MTC) devices in 5G will use the Non-orthogonal multiple access (NOMA) technology for massive connections. These devices switch between the transmission…
Effective Capacity Analysis in Ultra-Dense Wireless Networks with Random Interference
Yu Gu, Qimei Cui, Yu Chen +3
Ultra-dense networks (UDNs) provide a promising paradigm to cope with exponentially increasing mobile traffic. However, little work has to date considered unsaturated traffic with…
Use of Two-Mode Circuitry and Optimal Energy-Efficient Power Control Under Target Delay-Outage Constraints
Jinkun Xu, Yu Chen, Hao Chen +2
An accurate energy efficiency analytical model based on a two-mode circuitry was recently proposed; and the model showed that the use of this circuitry can significantly improve a…
