A known problem in radio resource management in wireless local area networks using the IEEE 802.11 protocol is the neighborhood capture effect. This effect severely reduces the protocol efficiency when multiple sets of stations are co-located. It is one of the most critical aspects of overlapping and coexisting basic service sets. Here, we discuss the problem with focus on quality of service. By using techniques based on the new upcoming IEEE 802.11e, which is an extension of the IEEE 802.11 for the provisioning of quality of service, the neighborhood capture effect can be reduced, and data throughput and delivery delays can be improved. We show simulation results indicating that in certain scenarios, with a simple synchronization and slotting scheme, the problem is significantly reduced.
