Advances in Wireless M2M and IoT: Rapid SDR-prototyping of IEEE 802.11ah
نویسندگان
چکیده
We propose demonstrating an IEEE 802.11ah wireless local area network (WLAN) prototype that is configured as a self-contained machine-2-machine (M2M) wireless sensor system. Because the IEEE 802.11ah protocol standardization is under way, no commercial-off-the-shelf (COTS) IEEE 802.11ah Wi-Fi product is available yet. However, the proposed prototype has the potential to solve this issue and allows an over-the-air protocol performance assessment. A software defined radio (SDR) platform is developed, that consists of universal software radio peripheral (USRP) devices combined with radio frequency (RF) daughter-boards operating at the 900 MHz ISM-band. Additionally, the 2×2 multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) operation is realized, which requires modifications on the PHY implementation. This demo provides a practical and cost-efficient research platform for the upcoming IEEE 802.11ah WLAN and its use in M2M and Internet of Things (IoT) wireless long-range access networks.

متن کاملAn Authentication and Key Management Mechanism for Resource Constrained Devices in IEEE 802.11-based IoT Access Networks
Many Internet of Things (IoT) services utilize an IoT access network to connect small devices with remote servers. They can share an access network with standard communication technology, such as IEEE 802.11ah. However, an authentication and key management (AKM) mechanism for resource constrained IoT devices using IEEE 802.11ah has not been proposed as yet. We therefore propose a new AKM mechan...
