IEEE 802.16 standard provides resources to both service classes Constant Bit Rate (CBR) and Variable Bit Rate (VBR). These services require enough resources to transmit data efficiently. In this paper, a Service Based Fair Resource Allocation (SBFRA) Mechanism is proposed, for assessing the required service from Subscriber (SS) along with the channel condition. The proposed model evaluates the required additional resources in order to provide the required service to SS. In this proposed model, a Priority Queue Scheduling Methodology is presented in order to provide additional resources as per channel condition. A comparison is made with and without the proposed model on both traffic, CBR and VBR. The experiments show that the proposed design manages the user request by providing them additional resources as per requirement. The requestsare handled in Priority Queue Scheduling based mechanism. Results show that an improvement is achieved by providing the additional resource on fair scheduling basis. To achieve the required performance for fairness there is a compromise on delay.
