Abstract:
3G Long Term Evolution is an emerging and promising technology that aims at providing broadband ubiquitous internet access and improving multimedia services. This is achieved through streamlining the system for packet services since long term evolution is an all Internet protocol based network. The fact that 3G long term evolution is a packet based network brings along some improvements in the form of higher bit rates, lower latencies, and a variety of service offerings. However, some technical challenges are expected to arise when voice traffic is transmitted over a long term evolution network. This has become an interesting area of research and different types of resource management schemes have been developed which are quite challenging and complex. In this paper, we analyze the complexity and fairness of our proposed scheduling scheme for voice over internet protocol in 3G long term evolution called voice over internet protocol optimization scheduling algorithm. We compare it with other algorithms in literature. There is second order complexity in the number of users based on quality feedback, queue length metrics, and there is linear complexity in resource blocks using voice over internet protocol optimization scheduling algorithm. Simulation results also showed approximately 10 – 20 percent improvement in fairness and performance based on the fairness index and throughput
