Query: Spatiotemporal Stochastic Modeling of IoT Enabled Cellular Networks:
  Scalability and Stability Analysis   The Internet of Things (IoT) is large-scale by nature, which is manifested by
the massive number of connected devices as well as their vast spatial
existence. Cellular networks, which provide ubiquitous, reliable, and efficient
wireless access, are natural candidates to provide the first-mile access for
the data tsunami to be generated by the IoT. However, cellular networks may
have scalability problems to provide uplink connectivity to massive numbers of
connected things. To characterize the scalability of cellular uplink in the
context of IoT networks, this paper develops a traffic-aware spatiotemporal
mathematical model for IoT devices supported by cellular uplink connectivity.
The developed model is based on stochastic geometry and queueing theory to
account for the traffic requirement per IoT device, the different transmission
strategies, and the mutual interference between the IoT devices. To this end,
the developed model is utilized to characterize the extent to which cellular
networks can accommodate IoT traffic as well as to assess and compare three
different transmission strategies that incorporate a combination of
transmission persistency, backoff, and power-ramping. The analysis and the
results clearly illustrate the scalability problem imposed by IoT on cellular
network and offer insights into effective scenarios for each transmission
strategy.
