A study on optimization of polling schedule to minimize the number of frames for in-vehicle UWB wireless network

Abstract

This paper discusses a polling and scheduling method for UWB-based in-vehicle networks. In IEEE 802.15.4a/z, conveying as much sensor data as possible in a Physical layer Protocol Data Unit (PPDU) is more efficient. Therefore, this paper proposes a scheduling scheme that minimizes the number of frames to be transmitted by adjusting the readout phase of periodic sensor data. Compared to existing methods, our proposed method can aggregate sensor data into fewer frames, resulting in a decreased loss rate in our experiment.
