Performance Analysis of Contention Based Services with Bulk Transmission in IEEE 802.16 OFDMA Networks

摘要

With the development of wireless broadband access, OFDMA technology is widely used for the next generation telecommunication systems. In this paper, we focus on analyzing the performance of contention-based services in IEEE 802.16 OFDMA networks with bulk services. We derive various performance measures such as queue utilization in an subscriber station, probability of unsuccessful bandwidth request, and the mean service time of a packet. The accuracy of the proposed analytical model is validated by extensive simulations.
