Abstract

There are numerous high-speed access connections for mobile end-users, including Wi-Fi and Long Term Evolution (LTE), in reaction to the increasing demand for greater quality Voice over IP (VoIP) communication. The mixture of access connections offers a hybrid network environment in which end-users can switch from one to the other, whichever offers a greater level of VoIP service quality (QoS). In addition to the sort of access link, VoIP codecs are another important factor that directly impacts speech communication's of general QoS. Several networks have separate constraints and requirements due to intrinsic features. Taking these distinctions into account, the visualization and analysis of each codec's performance and behavior on its underlying network will result in a correct VoIP codec choice, resulting in ideal speech QoS for mobile end-users. This research proposes a technique for quantifying and analyzing the efficiency of various VoIP codecs in a hybrid LTE-802.11ac network where two respective network interface cards are available to mobile end-users. The goal is to discover the codecs that best fit LTE and 802.11ac networks and optimize the VoIP communication. The NS3 tool is used to create and execute a range of separate scenarios that accurately measure different QoS performance metrics. The findings collected indicate the comprehensive effect of codecs on the speech communication QoS for both LTE and 802.11ac users as well as the significance of the VoIP codec selection process for each network.
