Scheme for Joint Optimization of MAP Overhead and System Throughput in Message Based MIMO-OFDM Systeband access systems are needed to minimize the MAP overhead since the excessive MAP overhead causes degradation of system throughput. Increasing the size of resource allocation unit can reduce MAP overhead. However, multiuser diversity gain becomes smaller as the size of resource allocation unit inc

Simulating Mobile Ad-Hoc Networks in City Scenariosf network protocols. We demonstrate the usefulness of the platform for performance evaluations by modeling a mobile application in a simulated environment of Stuttgart downtown. We show that it helps identifying application problems before deployment.

Comprehensive Analytical Models to Evaluate the TCP Performance in 802.11 WLANss between TCP and MAC protocols. Results obtained from the models are compared among themselves and against simulations, and show the accuracy and the superior simplicity of the proposed models with respect to previously published work.

State of the Art Prepaid Charging for IP Serviceso implement prepaid charging, have been evaluated. Therefore, to enable prepaid charging for QoS-enabled and all-IP environments, key concerns for a future IP service provisioning have been determined, which remain infeasible with existing prepaid solutions, and the evaluation lead to a new scheme proposed.
