DCF and EDCA throughput improvement using Selective Anomalous Slot Avoidance (SASA)

Abstract

In DCF and EDCA schemes, the number of collisions increased caused the number of anomalous slots also increased. These conditions caused the average duration of collision will be much longer and result in a decreased network throughput. In this paper we have proposed SASA scheme to avoid anomalous slot after the collision. Simulation results show SASA scheme produces higher throughput compare to DCF and EDCA schemes.
