This paper analyzes the achievable secrecy rate in a millimeter wave (mmWave) multi-input single-output (MISO) ad hoc network in the presence of colluding eavesdroppers. First, using the tools of stochastic geometry, the mathematical analysis of the average achievable secrecy rate is performed, taking into consideration the impact of blockage and Nakagami-m fading. Moreover, a multi-array artificial noise transmission technique is applied at the typical transmitter (Tx-AN) to enhance the average secrecy rate. Consequently, the mathematical expression of the average achievable secrecy rate for mmWave MISO ad hoc network with Tx-AN technique is presented. Numerical and simulation results show that, at given values of colluding eavesdroppers’ intensity and total transmit power, using Tx-AN technique achieves 56.4% improved average secrecy rate over that without. Furthermore, by applying the Tx-AN technique, increasing the colluding eavesdroppers’ intensity provides no negative impact on the average secrecy rate. However, without the AN technique, the average secrecy rate faces a fast degradation when the intensity of colluding eavesdroppers increases. The results therefore show that the Tx-AN technique is a useful technique to enhance the secrecy performance of mmWave MISO ad hoc network in the presence of colluding eavesdroppers.
