Performance analysis of best-effort service in saturated ieee 802.16 networks

Abstract

The IEEE 802.16 standard is a promising technology for the fourth-generation mobile networks and is being actively promoted by the Worldwide Interoperability for Microwave Access (WiMAX) Forum: an industry-led consortium. Among the various service classes supported in the standard, best-effort service is expected to be the major service class subscribed to by users due to its operational simplicity and lower charging rate compared with other service classes. In this paper, we investigate the throughput and packet-access-delay performance of best-effort service using the contention-based bandwidth request mechanism in a saturated IEEE 802.16 network. In particular, we develop a simple fixed-p..
