Throughput Analysis of CSMA With Imperfect Collision Detection in Full Duplex-Enabled WLAN

As an alternative to carrier sense multiple access (CSMA) with collision avoidance in half-duplex wireless local area network (WLAN) that incurs heavy control overhead, full-duplex WLANs enabling wireless collision detection (WCD) by simultaneous carrier sensing and data transmission are gathering tremendous research interest. Although CSMA with perfect WCD leads to large throughput enhancements, actual performances will highly depend on the wireless environment, user distributions, and resulting collision patterns. Hence, we derive the achievable system throughput accounting for imperfect WCD, and evaluate the throughput gains that can be expected from CSMA with imperfect WCD over conventional random access protocols.
