To attain the Voice over Internet Protocol (mVoIP) for mobile framework through adaptively in Software Defined Networking (SDN) in a more better and efficient manner. The key parameters or obstacles that come across in improving the Quality of Experience of mVoIP can be optimization of path of the data during forwarding for flows in VoIP and selection of optimized codes for the network congestion...
Wireless Local Area Network (WLAN) has enabled greater communication capabilities compared to LAN counterpart. However, when it comes to quality of service (QoS), WLAN has lower reliability, where it has higher latency and packet-loss, especially for real-time streaming applications such as voice over internet protocol (VoIP) and multimedia. Thus, improving QoS in WLAN is a major research challenge,...
In this paper, we propose a QoS control mechanism that estimates the congestion of wireless channels in the wireless LAN and evaluates the voice packet drop ratio based on the estimated congestion status. The mechanism adjusts the voice packet transmission rate according to the evaluated packet loss ratio, and thereby resolves the congestion situation. In this way, the mechanism can keep users' quality...
This paper presents the results of our computer simulation for delays experienced by voice packets over WiMAX 802.16e protocol running over an enterprise packet network connected to public internet. In the simulation we analyzed the effect of packet size, core network link speed, Internet service provider link speed, wireless network link speed, wireless distance, base station range, and distance...
