SUMMARY:PhD thesis defense of Pierre POPINEAU "Study of the dynamics of
 spatial point processes in wireless communication networks"
DESCRIPTION:Thanks to the new paradigms introduced in the latest generation
 of wireless networks\, expectations concerning service time\, latency and
 network performance have increased. To model such networks\, point process
 theory and stochastic geometry have proven to be useful as they provide a
 versatile and robust framework to obtain results when working with such
 wireless networks. Adding to this Markov dynamics to model connections and
 service times completes this framework to analyze such wireless networks.
 The first contribution of the work presented in this thesis lies in the
 analysis of service differentiation: 5G NR networks have introduced
 bandwidth partitioning as a tool to increase network performance. Under
 this network setup\, not all users interfere with each other with the same
 power: users transmitting with a broader transmitting frequency spectrum
 will have a larger bandwidth\, but they will also encounter more
 interference from the other users in the network. In contrast\, users with
 a narrower spectrum will experience less interference. We define a
 Markovian framework to study such a multiclass spatial birth-and-death
 process\, and we describe its stability region. For such systems\,
 properties of the stationary regime are analyzed\, such as moment measures
 or statistical clustering\, leading to a better understanding of these
 dynamics. The second problem we look into is mobility\, which has become an
 important feature in wireless networks due to the use of highly directional
 antennas. Using a simple architecture for a two-tier cellular network\, we
 study two families of association policies: a first family which only
 relies on user mobility\, and the second offers a trade-off between network
 geometry and user mobility to increase network performance. These policies
 are then compared to a classical max-power association policy to assert
 their performance.\n
