Abstract [en]

Long Term Evolution (LTE) is the last step towards the 4th genera-tion of cellular networks. This revolution is necessitated by the un-ceasing increase in demand for high speed connection on LTE net-works. This thesis mainly focuses on performance evaluation of end-to end delay (E2E) for VoIP in the LTE networks. In the course of E2E performance evaluation, simulation approach is realized using simulation tool OPNET 16.0. Three scenarios have been created. The first one is the baseline network while among other two, one consists of VoIP traffic solely and the other consisted of FTP along with VoIP. E2E delay has been measured for both scenarios in various cases under the varying mobility speed of the node. Furthermore, packet loss for two network scenarios has been studied and presented in the same cases as for E2E delay measurement. Comparative performance analysis of the two networks has been done by the simulation output graphs. In light of the result analysis, the performance quality of a VoIP network (with and without the presence of additional network traffic) in LTE has been determined and discussed. The default parameters in OPNET 16.0 for LTE have been used during simulation.
