Numerical analysis of the power saving with a bursty traffic model in LTE-Advanced networks

In the past few years, it's observed that cellular operators have experienced a fast growth of mobile broadband subscribers and traffic volume per subscriber. Simultaneously, operators are moving from a single to a multi-service offering by adding new services. This chapter presents a survey of the Quality of Service (QoS) drivers in LTE and LTE-Advanced, focusing on IP Frameworks and IP Services. It also includes a detailed list and description of the resource management mechanisms, such as power saving, admission control, scheduling and resource allocation that play a vital role in QoS. The authors describe the State-of-the-Art in IP frameworks and Services such as video, VoIP, Video on Demand (VoD). Also, resource management mechanisms are described such as Energy efficiency, admission control, and scheduling. In the end, the authors mentioned the future directions about QoS in 5G networks.

Place And Route

C-based cycle-accurate simulations are used to evaluate the performance of a Network-on-Chip (NoC) based on an improved version of the modified Fat Tree topology. The modification simplifies routing further and guarantee orderly reception of packets without any loss of performance. Several traffic models have been used in these simulations; Bursty and non-bursty traffic with uniformly-distributed destination addresses and non-uniformly-distributed destination addresses. A simple new traffic model has been developed for generating non-uniformly-distributed destination addresses. This model is general enough to be used in developing new NoC architectures and captures universally accepted place-and-route methodologies. Simulation results are used to illustrate how the hardware resources of a modified Fat Tree NoC can be minimized without affecting the network performance. The performance of a NoC with regular Mesh topology was also evaluated for comparison with the modified Fat Tree topology.
