Poster: A scheduling method for V2V networks using successive interference cancellation

Abstract

In this paper, we propose a scheduling method with successive interference cancellation (SIC) for vehicle to vehicle (V2V) networks to improve the reliability and the capacity. SIC is a multi-user detection technique that repeatedly decodes the multiple signals by cancelling the strongest signal by using the detected signal in the previous step. In the proposed distributed scheduling method, the time slots are allocated by using the location information of the vehicles and the estimated signal to interference plus noise ratio (SINR) at multiple receivers for effectively working SIC. The location information can be known by the iterative beacon signal transmitted from each vehicles. The proposed method enables simultaneous detection by SIC. We compare the performance of the proposed scheduling method with random allocation method under multiple peer to peer unicast communication. In addition, we set SINR margin to slot allocation for improving robustness of SIC.
