Additional Resource Allocation for improving Fairness in WiMAX
Abstract: IEEE 802.16 standard
provides resources to both service classes Constant Bit Rate (CBR) and Variable
Bit Rate (VBR). Both of these services required enough resources to transmit
data efficiently.Considering available literature there is a gap to provide
additional resources for fulfillment of the required service class.In this
paper we propose a Service Based Fair Resource Allocation (SBFRA) Mechansim, 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 additional 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 with delay.
