Abstract

In recent years, there has been a lot of interest in using wireless local area networks (WLAN) for voice communications with the expanded coverage of hot spots. This paper describes packet aggregation method that increases the throughput of WLAN for voice communication by decreasing the overhead of backoff at the beginning of each packet transmission. Aggregation allows AP to acquire the channel and send its packets inside a multicast packet or back-to-back. Implementation and analysis of frame aggregation show that it improves the performance of voice over IP (VoIP) operating on IEEE 802.11 considerably
