Performance Analysis of ARQ with Opportunistic Scheduling in IEEE 802.16 Networks

As a promising broadband wireless access standard, IEEE 802.16 specified some advance physical layer techniques and media access control layer protocols, which pose many fundamental differences in terms of automatic repeat request (ARQ) mechanism, scheduling scheme, and resource allocation, compared with those done in many previous works. In this paper, we analyze the performance of ARQ in IEEE 802.16 networks by jointly considering the opportunistic scheduling scheme, where the delivery delay and goodput are investigated as two performance metrics. Simulation results are given to verify the proposed analysis model.
