Abstract
LTE is the evolution of the Universal Mobile Telecommunications System (UMTS). It allows mobile users to access Internet through their devices (mobile telephones, laptop…). LTE intends to deliver high speed data and multimedia services to next generation. In the coming years LTE mobile broadband technology will be widely used by devices such as notebooks, smart phones, gaming devices and video cameras. The Long-Term Evolution provides a high data rate and can operate in different bandwidths ranging from 1.4MHz up to 20MHz. LTE supports high peak data rates (100 Mb/s in the DL and 50 Mb/s in the UL), low latency (10ms round-trip delay), improves system capacity and coverage and reduces operating costs. Furthermore it supports Multiple Input Multiple Output (MIMO) and allows seamless integration with existing systems.
Voice over Long Term Evolution (called VoLTE) is always a main service that brings a big benefit for mobile operators. However, the deployment of VoLTE is very complex, specially for guaranteeing of Quality of Service (QoS) to meet quality of experience of mobile users.
The purpose of the project is to examine the quality of service for a range of different data in terms of priority through the application of four types of scheduling algorithms namely: Robin Round, the scheduling algorithm that takes into account the channel and the quality of the service "Priority Set" , Channel and QoS Aware " And the Fair Proportional algorithm, for the transmission of these data via the VOLTE network and to compare the results of these algorithms and their effectiveness during the cumulative increase For network users.
The schedulers are simulated using real-time packets with a various channel condition of user equipment (UE) in NS3 simulator to test the performance of each scheduler
