Theoretical analysis for CSMA/CA-based wireless full duplex networks

Abstract

Full Duplex (FD) communication can potentially double the throughput of a point-to-point link in wireless communication. Additionally, FD communication can mitigate collisions induced by hidden nodes. Though exchanging control frames also mitigate hidden node collisions, FD communication has a smaller overhead for one data transmission than the control-frame scheme. Although FD communication is expected to provide system-performance improvement, the enhancement highly depends on its network topology or system parameters. Besides, it is not easy work to comprehend the relationships between system parameters and network performance. Theoretical analysis is useful for evaluating network performance and the optimal design for the system. This paper introduces theoretical analysis for Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA)-based wireless FD networks, mainly author's researches, and discusses their performance. In this paper, star-topology single-hop networks and string topology multi-hop networks are considered as analysis subjects. This paper evaluates FD communication potential for each network through the analytical model by comparing network performances with exchanging control frames and FD communication.
