Abstract
. This paper presents a high throughput and low latency wireless with efficient bandwidth transmission, particularly for Medical Internet of Things (MIoT) applications. The proposed method is obtained by employing shorter OFDM (Orthogonal Frequency Divison Multiplexing) symbol duration which corresponds to shorter packet transmission. This can be realized by reducing subcarrier spacing and allowing to use of a smaller number of sample data in the time domain while maintaining sampling rate frequency. Furthermore, the proposed scheme can transmit more data frames twice within the original time slot duration, hence, it can enhance the throughput without expanding the bandwidth utilization. The evaluation results of 20 MHz and 40 MHz bandwidth cases show throughput improvement by around 2.3 and 2.6 times compared to the conventional ones. In addition, the proposed scheme also provides low latency transmission by reducing the transmission time by around 50%. The corresponding hardware implementation is also provided with low-complexity hardware resources. Hence, the proposed system can be used for IoT systems with main considerations on low latency, high throughput, bandwidth efficiency, and low power consumption.
