Abstract
It is well known that in case of high density deployments, Wi-Fi networks suffer from serious performance impairments due to hidden and exposed nodes. The problem is explicitly considered by the IEEE 802.11ax developers in order to improve spectrum efficiency. In this paper, we propose and evaluate the joint usage of dynamic sensitivity control (DSC) and time division multiple access (TDMA) for improving the spectrum allocation among overlapping 802.11ax BSSs. To validate the solution, apart from simulation, we used a testbed based on the Wireless MAC Processor (WMP), a prototype of a programmable wireless card.
