Abstract
This paper proposes a fast beam tracking algorithm for wireless backhauling to moving vehicles having access point function. The basic concept is developed earlier as the adaptive moving network to track to spatio-temporal traffic demand fluctuation. This architecture necessitates wireless connection between vehicular access points and network side. Further, wireless backhaul requires high capacity as well as coverage, therefore use of millimeter wave and massive array beamforming is essential. Our backhauling strategy focuses on the movable region of vehicles on the road to simplify the beam tracking algorithm. Simulative evaluation verifies its capability even when the vehicle speed dynamically changes.
