End-to-End Delay Performance for VoIP on LTE System in Access Network

Abstract

Abstract. The desire Quality of Service (QoS) of Voice over Internet Protocol (VOIP) is of growing importance for research and study Long Term Evolution (LTE) is the last step towards the 4 th generation of cellular networks. This revolution is necessitated by the unceasing increase in demand for high speed connection on LTE networks particularly for under variable mobility speed for VoIP in the LTE. This paper mainly focuses on performance of VOIP and the impact of resource limitations in the performance of Access Networks particularly important in regions where Internet resources are limited and the cost of improving these resources is prohibitive. By determine rate communication quality, is determined by end to end delay on the communication path, delay variation, packet loss. These performance indicators can be measured and the contribution in the access network can be estimated using simulation tool OPNET Modeler in varying mobility speed of the node. The overall performance of VOIP thus greatly improved significantly by deploying OPNET Modeler.

A Comparative Analysis of Packet Scheduling Schemes for Multimedia Services in LTE Networks

“…2(a), it can be concluded that all the schemes failed to meet the QoS requirements of video streaming service. In other hand, a VoIP user is satisfied if more than 98% of its voice packets are delivered successfully [13]. From Fig.…”

“…For quality voice and video service application such as Skype and Google+ Hangout, the packet E2E delay should not exceed 150 ms to evaluate that the quality of the created VoIP calls is accepted [13]. The result obtained from the video and VOIP quality assessment for delay variations are plotted in Fig.…”
