Abstract

In this paper, we investigate a directional millimeter wave transmission scheme for vehicle-to-vehicle communications in an ad-hoc network when inaccurate location information is given. Considering the location inaccuracy, we propose an algorithm for both beam alignment and transmit probability adjustment. Numerical evaluations verify that the proposed algorithm produces more energy-efficient transmission with lower transmit probability while guaranteeing an SINR requirement.

reduced sum of transmit probabilities by 77.6% compared to the omni-directional transmission without adjusting transmit probabilities. We also verify that fine beam control enables us to improve energy efficiency compared to the case of random beam widths. With the additional beam control and probability adjustment, the sum of transmit probabilities is reduced by 16.7% compared to the case of adjusting only transmit probabilities. IV. CONCLUSION In this paper, we propose an ALOHA based directional transmission scheme for V2V communications when inaccurate location information is given. Considering the error bound of location information, we adjust beam widths and transmit probabilities for energy-efficient transmission. We find that narrow beam widths obtained from fine beam alignment lead to more energy-efficient transmission with lower transmit probabilities while guaranteeing SINR requirements. Future research will be generalized our algorithm in N -pair scenario and also considered the beam-level beam width of receiver.
