In this paper, the performance of unsolicited grant service (UGS) connections defined in IEEE 802.16 Std. is investigated. A simple admission control strategy based on the periodic exhaustive service principle is first introduced to provide Quality of Service (QoS) satisfaction for such connections. The task of system parameter selection and performance evaluation for the UGS flows is tackled. In particular, the maximum retransmission limit that works along with the embedded Automatic Repeat reQuest (ARQ) mechanism is emphasized. A novel transferred model is formulated such that the lossy characteristic of the wireless channels in real networks can be completely engineered by way of the traffic arrival pattern and the size of the messages in the proposed model. Significant merits and efficiency have been identified in the proposed model through extensive simulation, where a complete match between the analytical and simulation results is observed.
