IEEE 802.16 standard suite defines two main polling modes, unicast polling and contention-based polling, to support different bandwidth allocation requirement. Although the specification introduces four service classes to adaptively implement the polling mechanisms for different type of traffics, it does not specify exactly how these polling modes could be used for efficient bandwidth allocation....
In order to support different bandwidth allocation requirements from different applications, IEEE 802.16 standard suite defines two main polling modes, unicast polling and contention-based polling. Although the specification introduces four service classes to adaptively implement the polling mechanisms for different type of traffics, it does not specify exactly how these polling modes could be used...
IEEE 802.16 standard suite defines two main polling modes: unicast polling and contention-based polling. These polling modes are adaptively adopted by different service classes in order to guarantee different performance requirements from different applications, in which the nrtPS (non real-time Polling Service) service class is defined to allow to adopt both the two polling modes. However, the standard...
IEEE 802.16 standard suite defines the air interface specifications for fixed and mobile broadband access in wireless metropolitan area networks. Although it has been well-defined, efficient bandwidth allocation still remains as open issue. In this paper we analyse and develop a mathematical model ta evaluate the uplink throughput of the contention-based and delay-tolerant applications in IEEE 802...
