The wireless local area network (WLAN) is one of the potential candidates for IoTs technology to connect billions of smart devices. Long-range WLAN is widely deployed in dense networks as an alternative to cellular networks or satellite internet access because of its low cost, high performance, and existing ecosystem. However, due to the nature of unregulated communications in industrial, scientific, and medical (ISM) bands, WLANs experience interferences from other radios such as radars and frequency hopping devices. Once interference is detected at a WLAN device, the channel is avoided and other channels become crowded. Thus, it degrades network throughput and channel utilization. In this paper, a secure inter-frame space communication system design is proposed for WLANs to share the ISM bands with other radio systems that generate periodic radio signals. The proposed secure inter-frame communication scheme achieves the goal by designing accurate radar detection and secure inter-frame space communication. The simulation results demonstrate that the proposed scheme significantly increases the receiver sensitivity and user datagram protocol throughput.<\/jats:p>","DOI":"10.3390\/fi10060047","type":"journal-article","created":{"date-parts":[[2018,6,4]],"date-time":"2018-06-04T12:14:30Z","timestamp":1528114470000},"page":"47","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Secure Inter-Frame Space Communications for Wireless LANs"],"prefix":"10.3390","volume":"10","author":[{"given":"Il-Gu","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Convergence Security Engineering, Sungshin University, 02844 Seoul, Korea"}]}],"member":"1968","published-online":{"date-parts":[[2018,6,4]]},"reference":[{"key":"ref_1","unstructured":"Jun, J., Peddabachagari, P., and Sichitiu, M.
