Beam Tracking in Switched-Beam Antenna System for V2V Communication

Abstract

This paper presents the proposed switched beam antenna system for V2V communication including optimum antenna half power beamwidth determination in urban road environments. SQP optimization method is selected for the computation of optimum antenna half power beamwidth. In addition, beam tracking algorithm is applied to guarantee the best beam selection with maximum RSSI. The results present the success of the proposed system with the increasing of V2V performance metrics. Also, V2V data dissemination via the proposed system introduces the enhancement of V2V link in terms of RSSI, PER, BER,Tsafe, andRsafe. The results indicate the improvement of V2V link reliability. Consequently, the road safety is improved.
