Service based fair resource allocation model (SbFRAM) in WiMAX

Two broader categories of the services are introduced in the paradigm of WiMAX. In IEEE 802.16 standard has added these services and called them as Constant Bit Rate (CBR) and Variable Bit Rate (VBR). Both of these services designed for real time and non real time traffic. As per literature available there is a gap to provide additional resources to fulfill the required service class from the user. In this paper we propose a Service Based Fair Resource Allocation Model (SbFRAM), for evaluating the required service from Subscriber (SS) along with the channel condition. Our proposed model evaluates, for providing the required service to SS how much additional resource will be required. In this model we introduced Priority Queue Scheduling Methodology for providing additional resources as per channel condition. In this paper we made comparison with and without proposed model on both traffic, CBR and VBR. We experiment that our proposed model manages the user request by providing them extra resources as required for satisfaction. Their request handled in Priority Queue Scheduling based mechanism. Results shows, that we achieve improvement by providing the additional resource on fair scheduling basis. To achieve the required performance for fairness we have to compromise on delay.
