Abstract:
|
The need for higher data rates and improved coverage has led to massive and uncoordinated deployments
of IEEE 802.11 based WLAN Access Points in geographically limited areas that has resulted in increased interference
with reduced area throughput. Recently, the IEEE 802.11 working group has continued efforts to cater the
aforementioned problems by creating the IEEE 802.11ax Task Group, TGax (which aims to improve performance in
dense environments). TGax has been actively involved in the design of Clear Channel Access (CCA) modification
schemes, where Dynamic Sensitivity Control (DSC) algorithm has been proposed as one of the key innovative
technologies to increase the spectral reuse. However, DSC scheme has drawbacks: increase in frame collisions as
well as hidden node count. In this paper, we propose the combined usage of DSC along with an intelligent mechanism
to enable RTS/CTS on selected stations within densely deployed WLAN network. We present methods to select
stations for 4-way handshake and indicate considerable gains (up to 60%) when a network utilizing the aforementioned
method is compared with legacy IEEE 802.11 operation. |
