Abstract :
The EDCA access mechanism of the 802.11e standard supports legacy DCF stations, but the performance of high priority traffic is substantially degraded in their presence. In a previous letter we proposed the ACKS technique to mitigate the impact of legacy stations and studied this technique under high priority data traffic. In this letter we analyze the suitability of the ACKS technique for protecting voice traffic. Results show that voice performance is significantly improved as a result of using this technique
