RT Conference Proceedings T1 VoIPiggy: Implementation and evaluation of a mechanism to boost voice capacity in 802.11 WLANs A1 Salvador, Pablo A1 Gringoli, Francesco A1 Mancuso, Vincenzo A1 Serrano Yáñez-Mingot, Pablo A1 Mannocci, Andrea A1 Banchs Roca, Albert AB Supporting voice traffic in existing WLANs results extremely inefficient, given the large overheads of the protocol operation and the need to prioritize this traffic over, e.g., bulky transfers. In this paper we propose a simple scheme to improve the efficiency of WLANs when voice traffic is present. The mechanism is based on piggybacking voice frames over the acknowledgments, which reduces both frame overheads and time spent in contentions. We evaluate its performance in a large-scale testbed consisting on 33 commercial off-the-shelf devices. The experimental results show dramatic performance improvements in both voice-only and mixed voice-and-data scenarios.
