Abstract
The diversity of fifth generation (5G) network
use cases, multiple access technologies, and network
deployments requires measures of network robustness
that complement throughput-centric error rates. In
this paper, we investigate robustness in nonorthogonal
multiple access (NOMA) 5G networks through temporal
network theory. We develop a graph model and
analytical framework to characterize time-varying
network connectedness as a function of NOMA
overloading. We extend our analysis to derive lower
bounds and probability expressions for the number
of medium access control frames required to achieve
pairwise connectivity between all network devices. We
support our analytical results through simulation.
