Query: SDN - Architectural Enabler for Reliable Communication over
  Millimeter-Wave 5G Networks   Millimeter-wave (mmWave) frequency bands offer a new frontier for
next-generation wireless networks, popularly known as 5G, to enable
multi-gigabit communication; however, the availability and reliability of
mmWave signals are significantly limited due to its unfavorable propagation
characteristics. Thus, mmWave networks rely on directional narrow-beam
transmissions to overcome severe path-loss. To mitigate the impact of
transmission-reception directionality and provide uninterrupted network
services, ensuring the availability of mmWave transmission links is important.
In this paper, we proposed a new flexible network architecture to provide
efficient resource coordination among serving basestations during user
mobility. The key idea of this holistic architecture is to exploit the
software-defined networking (SDN) technology with mmWave communication to
provide a flexible and resilient network architecture. Besides, this paper
presents an efficient and seamless uncoordinated network operation to support
reliable communication in highly-dynamic environments characterized by high
density and mobility of wireless devices. To warrant high-reliability and guard
against the potential radio link failure, we introduce a new transmission
framework to ensure that there is at least one basestation is connected to the
UE at all times. We validate the proposed transmission scheme through
simulations.
