Query: Energy Efficient Barring Factor Enabled Extended Access Barring for IoT
  Devices in LTE-Advanced   Synchronized Random Access Channel (RACH) attempts by Internet of Things
(IoT) devices could result in Radio Access Network (RAN) overload in LTE-A.
3GPP adopted Barring Bitmap Enabled-Extended Access Barring (EAB-BB) mechanism
that announces the EAB information (i.e., a list of barred Access Classes)
through a barring bitmap as the baseline solution to mitigate the RAN overload.
EAB-BB was analyzed for its optimal performance in a recent work. However,
there has been no work that analyzes Barring Factor Enabled-Extended Access
Barring (EAB-BF), an alternative mechanism that was considered during the
standardization process. Due to the modeling complexity involved, not only has
it been difficult to analyze EAB-BF, but also, a much more far-reaching issue,
like the effect of these schemes on key network performance parameter, like
eNodeB energy consumption, has been overlooked. In this regard, for the first
time, we develop a novel analytical model for EAB-BF to obtain its performance
metrics. Results obtained from our analysis and simulation are seen to match
very well. Furthermore, we also build an eNodeB energy consumption model to
serve the IoT RACH requests. We then show that our analytical and energy
consumption models can be combined to obtain EAB-BF settings that can minimize
eNodeB energy consumption, while simultaneously providing optimal Quality of
Service (QoS) performance. Results obtained reveal that the optimal performance
of EAB-BF is better than that of EAB-BB. Furthermore, we also show that not
only all the three 3GPP-proposed EAB-BF settings considered during
standardization provide sub-optimal QoS to devices, but also result in
excessive eNodeB energy consumption, thereby acutely penalizing the network.
Finally, we provide corrections to these 3GPP-settings that can lead to
significant gains in EAB-BF performance.
