Cooperative NOMA for Throughput Enhancement of IEEE 802.11 WLANs: Channel Access Design and Performance Analysis
Keywords:
Cooperative communication, NOMA, CNOMA, Wi-Fi, WLANAbstract
In this research work, we propose cooperative non-orthogonal multiple access (CNOMA) based IEEE 802.11 wireless local area network (WLAN) and design a novel channel access scheme for CNOMA based WLAN. The proposed scheme integrates the resource efficiency of NOMA with cooperative relaying technique to enhance the throughput performance. In this scheme, stations (STAs) in the nearer regions act as the relay nodes for the STAs farther from the access point (AP). The novel channel access scheme form clusters by selecting STAs from the various data rate regions and allows nearest region nodes (cluster heads) alone to take part in the contention. This scheme also includes a procedure to select helper nodes from the high data rate regions. Additionally, we present an accurate analytical model for calculating the throughput of CNOMA based WLANs. Analytical and simulation results demonstrate that the proposed approach can significantly enhance the throughput performance of NOMA based WLANs.
