Contention-Based Transmission Coordination for Interfering BSs in Dense mmWave Networks

A contention-based collision avoidance protocol for dense millimeter-wave wireless networks in which base stations (BSs) use directional beamforming to provide downlink data streaming services to mobile users is proposed. The proposed protocol allows the BSs to contend with interfering BSs successfully transmit their downlink packets. Under the assumption that the inter-BS packet collisions incurred by inter-BS beamforming interferences are statistically predictable, a random number mechanism was used to decide whether to transmit the downlink packets. The proposed protocol’s effectiveness was then evaluated through extensive numerical simulations.
