PROJECT TITLE :

Hybrid MAC Protocol Design and Optimization for Full Duplex Wi-Fi Networks - 2018

ABSTRACT:

Recently, because of the advances in the self-interference cancellation technology, the in-band full-duplex (FD) capability has been demonstrated at Wi-Fi vary. But, the simultaneous uplink (UL) and downlink (DL) transmission could cause inter-user interference (IUI) and lead to decoding failure. Spectrum efficiency should also be thought-about in the construction method of the FD transmission. In this Project, we propose a hybrid [*fr1]-duplex/FD MAC protocol based mostly on a two-fold RTS/CTS rivalry resolution mechanism, in order to fully exploit the channel access opportunities provided by the simultaneous UL and DL transmissions. The noteworthy features of the proposed protocol lie in the subsequent 2 aspects. 1st, the protocol provides the flexibleness for the AP to decide the probability of constructing FD transmission, and then it adopts a second-fold of RTS/CTS mechanism to stop the created transmission from being plagued by the IUI. The second-fold rivalry and also the likelihood of constructing FD transmission are optimized separately to maximize the spectrum efficiency given completely different transmission demands. Simulation results show that the proposed MAC protocol achieves higher capacity compared with previous works, and the hybrid characteristic allows the FD Wi-Fi networks to satisfy with different system needs.
