Performance Analysis of Clustered LoRa Networks
Zhijin Qin, Yuanwei Liu, Geoffrey Ye Li +1
In this paper, we investigate the uplink transmission performance of low-power wide-area (LPWA) networks with regards to coexisting radio modules. We adopt long range (LoRa) radio…
Low-Power Wide-Area Networks for Sustainable IoT
Zhijin Qin, Frank Y. Li, Geoffrey Ye Li +2
Low-power wide-area (LPWA) networks are attracting extensive attention because of their abilities to offer low-cost and massive connectivity to Internet of Things (IoT) devices dis…
Resource Allocation in Wireless Powered IoT Networks
Xiaolan Liu, Zhijin Qin, Yue Gao +1
In this paper, efficient resource allocation for the uplink transmission of wireless powered IoT networks is investigated. We adopt LoRa technology as an example in the IoT network…
Non-orthogonal Multiple Access in Large-Scale Heterogeneous Networks
Yuanwei Liu, Zhijin Qin, Maged Elkashlan +2
In this paper, the potential benefits of applying non-orthogonal multiple access (NOMA) technique in -tier hybrid heterogeneous networks (HetNets) is explored. A promising new t…
