Abstract—The large packet header that IPv6 Telephony service uses has resulted in squandering a significant portion of bandwidth available on the IEEE 802.11n network. For example, the portion of the channel duration and capacity consumed by the packet header reaches 86% in IPv6 Telephony over IEEE 802.11n networks. IPv6 Telephony inventors are exerting extensive effort to handle this problem. This study contributes to the current effort by inventing a novel method called Pygmy. The heart of the Pygmy approach is built on using extra fields in the IPv6 Telephony packet’s header to maintain packet payload (i.e., voice data), thus decreasing or zeroing the payload of the IPv6 Telephony packet. Pygmy is a method that drastically cuts down on the enhanced bandwidth of IPv6 Telephony IEEE 802.11n networks. Also, unlike similar methods, the Pygmy method works in any network situation and doesn't add any extra work to the network devices. Findings indicate that the Pygmy approach is capable of decreasing the amount of wasted bandwidth caused by the G.723.1 codec by 23%. Therefore, the bandwidth and channel time of IPv6 Telephony over IEEE 802.11n networks can be successfully reduced by utilizing the Pygmy approach.
