Joint Space-Time Sparsity Based Jamming Detection for Mission-Critical mMTC Networks. (arXiv:2301.01058v1 [cs.CR])

For mission-critical massive machine-type communications (mMTC) applications,
the messages are required to be delivered in real-time. However, due to the
weak security protection capabilities of the low-cost and low-complexity
machine-type devices, active jamming attack in the uplink access is a serious
threat. Uplink access jamming (UAJ) can increase the number of
dropped/retransmitted packets and restrict or prevent the normal device access.
To tackle this vital and challenging problem, we propose a novel UAJ detection
method based on the joint space-time …
