Multi-stage algorithm for energy efficiency and data rate trade-off in imperfect CSI downlink NOMA systems
Abstract

Non-orthogonal multiple access (NOMA) is considered as a promising technique for improving energy efficiency (EE), spectral efficiency (SE), and data rate in 5 G and beyond wireless systems. Although power allocation plays a crucial role in ...

research-article
Physical layer security of multi-antenna relay assisted NOMA networks
Abstract

In this paper, the secrecy performance of one multi-antenna relay assisted non-orthogonal multiple access (NOMA) network is investigated when the relay employs either amplify-and-forward (AF) protocol or decode-and-forward (DF) protocol ...

Analysis of user association in multi-tier, multi-band heterogeneous cellular networks
Abstract

In this paper, the impact of the three-tier, multi-band heterogeneous networks (Het-Nets) performance, comprising of Terahertz (THz) tier, Sub-Terahertz (Sub-THz) tier, and millimeter wave (mmWave) tier has been modeled using stochastic geometry ...

research-article
Multi-attribute decision making approach for energy efficient sensor placement and clustering in wireless sensor networks: Multi-attribute decision making...
Abstract

Energy conservation is the most critical problem in wireless sensor networks due to its battery-operated tiny devices called sensors. These sensors are placed randomly in a region of interest to monitor certain events and targets. The random ...
