Abstract

In this letter, we propose a transmission opportunity (TXOP) tuning-based channel access scheme to enhance the performance of IEEE 802.11ah multi-rate NOMA-IoT networks. We consider the multi-rate NOMA-IoT network, which utilizes distributed coordination function (DCF) with restricted access window (RAW) mechanism at the data link layer and NOMA at the physical layer. We present an analytical model, and from the results, we observed that IEEE 802.11ah multi-rate NOMA-IoT network with the proposed channel access scheme provides significant improvement in throughput and connectivity compared to conventional IEEE 802.11ah multi-rate network. The proposed scheme gives enhanced throughput gain of 278.38% for N=1200 devices than IEEE 802.11ah NOMA-IoT network. The analytical results are validated with simulations.
