Abstract
The widespread and desirable features of IP and IEEE 802.11 networks have made these technologies a suitable medium for carrying voice over IP (VoIP). However, a bandwidth (BW) exploitation obstacle emerges when 802.11 networks are used to carry VoIP traffic. This BW exploitation obstacle is caused by the large 80-byte preamble size of the VoIP packet and a waiting time of 765 μs for each layer 2 VoIP frame. As a solution, IEEE 802.11n was consequently designed with a built-in layer 2 frame aggregation feature, but the adverse impact on the VoIP performance still needed to be addressed. Subsequent VoIP research has proposed numerous enhancements to the built-in IEEE 802.11n aggregation techniques. In this study, we analyse and propose enhancements to the BW exploitation and VoIP performance over IEEE 802.11n. We also recommend new techniques to enhance VoIP performance via IEEE 802.11n frame aggregation implementations. Furthermore, we contribute guidelines for creating a robust, suitable, and reliable aggregation technique for VoIP over the 802.11n standard.
Highlights
In recent years, the expansion of voice over IP (VoIP) applications, such as Zoom and FacebookMessenger, has become progressively omnipresent
This study has investigated the VoIP aggregation techniques over aggregation MAC protocol data unit (A-MPDU) 802.11n networks in terms of BW exploitation and VoIP performance
This study offers a set of primary guidelines that can be followed when designing a new aggregation technique
Summary
The expansion of voice over IP (VoIP) applications, such as Zoom and Facebook. The enormous universality of VoIP has numerous motivators, in which the most significant is the faint or free call cost Another notable incentive is the ability to conjugate voice with other useful features, including audio conferencing, text chatting, and video conversation. The large preamble size issue has been addressed by numerous approaches. One of these techniques is the VoIP packet preamble compression. We investigate the A-MPDU packet aggregation techniques of VoIP packets over the .11n standard. This study investigates the packet aggregation approach of VoIP packets over the .11n network.
