New generation of wireless networks, LTE and WiMAX, supports many services which consume a lot of resources (such as VOIP, Video Conference, Digital Video, Multimedia streams and online Multi-player Games). Supporting multi-media services in wireless communication systems provide new resource allocation challenges. Because of high loads in downlink, efficient resource allocation is vital in downlink rather than uplink. In LTE networks, different services need different Quality of Services (QoS). The aim of this article is evaluation of scheduling policies for real time and non-real time services in terms of three parameters. These parameters are throughput, fairness, and packet loss rate. The evaluations and comparisons of these parameters are done by simulation of the scheduling algorithms for a video traffic as a real time service and a web browsing traffic as a non-real time service.
