The effect of LoS blocking on drop of unicast connections in network with two types connections

The growing demand for wireless data transmission drives the adoption of millimeter waves to boost speed and reduce latency. However, their sensitivity to line-of-sight (LoS) blockages can disrupt communication and degrade service quality. This work studies the impact of LoS blockage on unicast connection losses in networks using both unicast and multicast connections. Unicast connections, transmitting data from one sender to one receiver, are highly sensitive to blockages, leading to data loss and reduced quality. Multicast connections are less a ected but require more complex resource management. A queuing system model is proposed to analyze blockage e ects, considering non-line-of-sight (nLoS) zones between the base station and users. It evaluates service quality, network performance for various modulation schemes, and estimates blocking probabilities based on user locations and moving obstacles. The focus is on minimizing unicast connection losses, o ering optimization recommendations for networks supporting both connection types, balancing resource e ciency and service quality.
