Some aspects of Blockchain-Enabled Radio Access Networks (B-RAN)
modeling: review and theoretical study
Abstract
The impressive growth of the demand for wireless services for 5G and
beyond, particularly encouraged by the Internet of Things, Internet of
Everything, etc., raised up the importance of the problems related to
the drastic increase (among others) of spectrum efficiency of the
systems. In this regard two opportunistic trends were recently discussed
by practical professionals and academicians: non-orthogonal spectrum
sharing (NOMA transmission) for user equipment (UE) at physical layer
level and decentralized Blockchain-enabled Radio Access (B-RAN) paradigm
at network layer label. Both of them promise a significant growth on the
transmission rate and the spectrum efficiency with low latency, etc. not
only for 5G networks, but further, towards 6G networks and so on.
Moreover, it is a fact that the number of published works for B-RAN
(some of them considered hereafter) is very impressive, however, the
attention to its modeling aspects is rather limited.
The following material is dedicated to present several theoretical
aspects of the small-scale modeling of B-RAN based on two well-known
principles: continuous time Markov stochastic processes with discrete
set of states for B-RAN modeling and self-similar processes for its
traffic modeling.
