Query: Wireless Avionics Intra-Communications: A Survey of Benefits,
  Challenges, and Solutions   In the aeronautics industry, wireless avionics intra-communications have a
tremendous potential to improve efficiency and flexibility while reducing the
weight, fuel consumption, and maintenance costs over traditional wired avionics
systems. This survey starts with an overview of the major benefits and
opportunities in the deployment of wireless technologies for critical
applications of an aircraft. The current state-of-art is presented in terms of
system classifications based on data rate demands and transceiver installation
locations. We then discuss major technical challenges in the design and
realization of the envisioned aircraft applications. Although wireless avionics
intra-communication has aspects and requirements similar to mission-critical
applications of industrial automation, it also has specific issues such as
complex structures, operations, and safety of the aircraft that make this area
of research self-standing and challenging. To support the critical operations
of an aircraft, existing wireless standards for mission-critical industrial
applications are briefly discussed to investigate the applicability of the
current solutions. Specifically, IEEE 802.15.4-based protocols and Bluetooth
are discussed for low data rate applications, whereas IEEE 802.11- based
standards are considered for high data rate applications. Eventually, we
propose fundamental schemes in terms of network architecture, protocol, and
resource management to support the critical avionics applications and discuss
the research directions in this emerging area.
