Interference in Millimeter-Wave Systems with Directional RTS/CTS Handshake

This paper presents a novel analysis of the directional RTS/CTS handshake mechanism using stochastic geometry, treating its impact as a thinning process in a spatial point process. We introduce unique thinning procedures based on the cosine antenna pattern, offering a more accurate representation of directional transmission in millimeter-wave networks. Through these models, we derive expressions for the intensity of concurrent transmitter processes and the mean interference. Our analysis provides key insights into how mean interference varies with system parameters such as antenna configuration and protection distance. Specifically, numerical results demonstrate that increasing the number of transmit antennas reduces interference, though diminishing returns are observed as the number of antennas grows.
