Performance Evaluation of the IEEE 802.16 ARQ Mechanism we analyze the key features and parameters of the ARQ mechanism. In particular, we consider a choice for the ARQ feedback type, a scheduling of the ARQ feedbacks and retransmissions, the ARQ block rearrangement, ARQ transmission window and ARQ block size. We run a number of simulation scenarios to

Analysis of a Cellular Network with User Redials and Automatic Handover Retrialsortant role in the system performance and therefore should not be ignored in its analysis. On the other hand, an exact Markovian model analysis of such systems has proven to be infeasible and resorting to approximate techniques is mandatory. We propose an approximate methodology which substantially

Expertise

On Evaluating a WiMAX Access Network for Isolated Research and Data Networks Using NS-2 WEIRD project, we evaluate the of IEEE 802.16 support for NS-2. We present several general but also specific issues, which are important in order to carry out reliable research based on these tools. In particular, we show in much detail where modules deviate significantly and even fail totally.

Effects of Spatial Aggregation on the Characteristics of Origin-Destination Pair Traffic in Funetmany exceptions. Gaussian assumption holds well for all OD pairs when the aggregation level is high enough, and we find an approximate threshold for OD pair traffic volume after which they tend to be Gaussian. Also the functional mean-variance relation holds better when the aggregation level is higher.

Users Dimensioning and Traffic Modelling in Rural e-Health Servicesns in the modelling of traffic distributions regarding the number of multiplexed users. The results obtained in this study permit an accurate users dimensioning, which is necessary to optimize the performance and to guarantee the QoS requirements in this kind of services where network resources are limited.
