DQRA-MIMO Protocol Design for Massive M2M Communications in
Intelligent Aircraft 2023-01-7071
The traditional centralized random access (RA) and data transmission (DT)
protocol used to transmit small-sized packets suffers from high signaling
overhead and low channel utilization. To cope with that, this paper proposes a
novel distributed queuing random access and data transmission protocol based on
multiple-input multiple-output (MIMO) technology for intelligent aircraft
scenarios. In the RA phase, the collided, successful, and idle states are
redefined according to the degree of freedom (DOF) in MIMO to utilize the RA
channel effectively. In the DT phase, the optimal number of simultaneously
transmitted M2M devices in the data queue is derived by the number of base
station’s antennas to enhance throughput and reduce signaling. Results reveal
that the proposed protocol can not only improve the efficiency of RA but also
increase the throughput and reduce the delay of DT with the aid of DoF in MIMO
while reducing the signaling overhead.
