Abstract

A new Dynamic Resource Allocator (DRA) architecture, based on a cross-layer framework, by using the control and signal channels implemented in the IEEE802.16e standard, is proposed. Commonly and a new designed packet schedulers are used in the performance evaluation of the DRA, by means of system level simulations under a realistic network layout, conducted on a proprietary C++ platform, fully compatible with the IEEE802.16e standard. Results are presented for the full queue and 3GPP Near Real Time Video (NRTV) traffic models and for the ITU PedB, PedA and VehA channel models for mobile speeds of 3 and 30 km/h. A newly designed scheduler based on the normalized (to the average) Signal To Interference plus Noise Ratio (SINR) is considered and its performance compared against the opportunistic Max CI and fair Round Robin.
