Abstract
For evaluation of the performance of wireless local area networks,
the radio characteristics between the access point (AP) and client
station (STA) in the same basic service set must be measured (BSS). Many
wireless networks coexist and may uncontrollably overlay in a specific
hotspot area because of the enormous demand for wireless services in
numerous applications. The performance of wireless radio channels is
affected because they are subject to interference from surrounding
energy, that direct impact on the throughput of both individual users
and networks. This problem can be resolved by a new spatial reuse IEEE
11ax feature that performs a clear channel assessment procedure between
the access point and client before assigning the channel for traffic,
thereby reducing channel collision and facilitating the wireless
network’s effective use of radio resources. Additionally, the usage of
radio channels would be limited on radio quality, resource availability
and the interference of overlaying networks. The work assesses the
performance of the spatial reuse feature using a clear channel
assessment approach in conjunction with some modulation and coding
schemes. After examination, we found that spatial reuse capability
improves the channel’s throughput performance by 18% to 20% higher
than conventional approaches for the lower Modulation and coding
scheme.
