Proposal of IEEE 802.11 wake-up control method using IEEE 802.15.4 for low energy consumption

Recently, Internet of Things (IoT) approaches to apply actual environment because of selling low cost sensors or improving wireless technology. IEEE 802.11 is formulated for Wireless LAN. They are able to send big size of data. However, the standard has problem increasing energy consumption to use high throughput. On the other hand, IEEE 802.15.4 is formulated for low energy consumption and low cost. The standard mainly focus on Wireless Sensor Network (WSN). The standard is suitable to transmit small data. In this paper, we propose a method that wake-up the IEEE 802.11 device using IEEE 802.15.4 data transfer for low energy consumption of IEEE 802.11 devices. In this paper, we proposed method that selects wireless standards by data size for decrease energy consumption. If big size of data are sent, the method selects IEEE 802.11. On the other hand, if small size of data are sent, IEEE 802.15.4 is selected. Based on actual machine experiment results, it was confirmed that there is a breakeven point at 40 Kbyte and 50 Kbyte.
