“…scale fading gains at the typical user from the interfering channel such that h s ∼ exp(1), from the interfering MBS such that h v,M ∼ Γ(U, 1) and from serving MBS for U users such that h o,M ∼ Γ(N − U + 1, 1) [26]. Here, the fading gain at eavesdropper at the separation distance x e from the serving BS is denoted by h e,M ∼ exp (1). Similarly, x s and x v are the distances measured from the typical user to small cell BS s ∈ Φ 2 and from the typical user to MBS v ∈ Φ 1 , and σ 2 is the thermal noise.…”

Massive multiple antenna systems in conjunction with millimeter (mmWave) communication have gained tremendous attention in the recent years owing to their high speed data delivery. However, security in these networks has been overlooked; thereby necessitating a comprehensive study. This paper analyzes the physical layer security performance of the downlink of a massive multiple-input multiple-output (MIMO)-based hybrid heterogeneous network (HetNet) where both mmWave and sub-6 GHz small cells coexist. Specifically, a tractable approach using stochastic geometry is proposed to analyze the secrecy outage probability, secrecy energy efficiency (SEE) and secrecy spectrum efficiency (SSE) of the hybrid HetNets. Our study further characterizes the impact of large antenna arrays, directional beamforming gains, transmit power, and cell density on the above mentioned secrecy performance measures. The results show that at low transmit power operation, the secrecy performance enhances for higher small cell density. It has also been observed that the higher directivity gains at mmWave cells lead to a drop in secrecy performance of the network; thus a tradeoff exists between better coverage or secrecy.This work is licensed under a Creative Commons Attribution 4.0 License.

Particularly, PLS in massive MIMO-enabled hybrid HetNets with mmWave small cells is important since the aforementioned networks present the most common deployment scenario for the future 5G communication networks. This paper analyses the PLS in massive MIMO-enabled hybrid HetNets by digging into unique advantageous properties of massive MIMO and mmWave channel.

“…Additionally, in 5G networks for increasing the network capacity, and provide reliable, secure, and lasting services, mmWave and massive multiple-input multiple-output (MIMO) can be considered as a solution [105]. This paradigm shift is analyzed in [106], in terms of network secrecy and network connection outage by demonstrating how base station density, mmWave small cells, and mu-MIMO affect each other through analytic models considering the base station density. They prove that if base station density is higher, then mu-MIMO-enabled networks along with mmWave small cells, dramatically decreases the network outage probability.…”
