A Unified Performance Model for Best-Effort Services in WiMAX Networks
نویسندگان
چکیده
Based on the work from the IEEE Working Group 802.16 and ETSI HiperMAN Working Group, the WiMAX (Worldwide Interoperability for Microwave Access) technology is defined by the WiMAX Forum to support fixed and mobile broadband wireless access. In the standard (IEEE 802.16 standard, 2009), it defines several air interface variants, including WirelessMAN-SC, WirelessMAN-OFDM, WirelessMAN-OFDMA and WirelessMAN-HUMAN. WiMAX networks can be operated in two different modes: point to multi-point (PMP) mode and mesh mode. Under the PMP mode, all traffics from subscriber stations (SSs) are controlled by the base station. Meshmode is a distributed architecture where traffics are allowed to route not only between SSs and the base station but also between SSs. In this chapter, we focus on the WirelessMAN-SC air interface operating in the PMP mode.

Performance Analysis of VoIP Codecs over WiMAX Networks
Real-time services such as VoIP are becoming popular and are major revenue earners for network service providers. These services no longer confined to the wired domain and extended over wireless networks. Although some of the existing wireless technologies can support some low-band width applications, the bandwidth demands of many multimedia applications exceed the capacity of these technologie...
متن کاملExperimental Evaluation of Multimedia Services in WiMAX
WiMAX is a new technology that can provide long distance broadband wireless access based on IEEE 802.16 standards. After a short overview of IEEE 802.16 and the WiMAX network architecture, we center on the Quality of Service (QoS) support for multimedia applications in WiMAX. Inherent QoS support is an important factor differentiating WiMAX from other wireless access technologies, but so far ha...
متن کاملInvestigation on IEEE 802. 16m Networks under Developed Error Model
Contention based bandwidth request mechanism is suggested for best effort services in WiMAX networks. The design of contention mechanism depends on the error model that reflects the transmission failure. In this paper, we have developed an error model by integrating the collisions due to contention, unavailability of bandwidth and channel error. The conventional exponential increase and exponen...
متن کاملA Unified Model for a Pricing Scheme in a Heterogeneous Environment of QoS-Controlled and Best Effort Connections
Starting from the mid ‘90s, a growing attention has been devoted to more and more sophisticated pricing models for telecommunication services and, in particular, it has become necessary to develop and test pricing methodologies to improve utility and fairness. A number of pricing models have been proposed and analyzed in the context of Quality of Service (QoS) guaranteed networks (e.g., ATM), a...
