An Efficient Data Forwarding Scheme for Internet of Things in Wi-Fi Networks


Recent IT technology trends are confronted with a new technological phenomenon. It is the intersection of technology and liberal arts. That is, IT convergence. Although the convergence trends will keep going in the future, there is the Internet of Things which are a new priming to accelerate these trends. A multitude of IoT devices will transmit various information through Internet, and the main channel of information flows will be a Wi-Fi networks. However, current Wi-Fi technology isn’t prepared to accommodate these data yet. Therefore, we propose the Efficient Data Forwarding Scheme (EDFS) to solve these problems. The proposed EDFS assigns a proper transmission opportunity (TXOP) to the IoT devices for supporting efficient data transmission. In the EDFA, Wi-Fi AP (Access Point) gives a calculated or pre-defined TXOP, which is suitable for the data transmission attributes of IoT device. Due to the fact that the data transmission feature of IoT devices isn’t the real-time traffic in the most cases. Based on the EDFA, a Wi-Fi AP can not only assign an efficient TXOP to a device, but also support various IoT device requirements within the Wi-Fi hotspot. We compared it with legacy Wi-Fi transmission scheme to prove the outperforming results by using the OPNet simulator.
