Fair Adaptive Bandwidth and Subchannel Allocation in the WiMAX Uplink
In some modern communication systems, as it is the case of WiMAX, it has been decided to implement Demand Assignment Multiple Access (DAMA) solutions. End-users request transmission opportunities before accessing the system, which provides an efficient way to share system resources. In this paper, we briefly review the PHY and MAC layers of an OFDMA-based WiMAX system, and we propose to use a N...
متن کاملFair uplink bandwidth allocation and latency guarantee for mobile WiMAX using fuzzy adaptive deficit round robin
The explosive demands of rich media applications with their diverse quality of service (QoS) requirements have continuously fuelled the needs for ever more powerful networks. One example of such a network is called WiMAX which is driven by WiMAX Forum based on IEEE 802.16 Wireless MAN standard. One of the issues that still remain open in WiMAX is the scheduling algorithm that goes to meet the Q...
متن کاملWeighted Fair Bandwidth Allocation for Adaptive Flows
Abstract— In this paper, we propose a gateway algorithm supporting both weighted fairness and queue management. Though some algorithms are proposed for fairness with queue management in the literature, they do not concern about the flow weight. Our proposed algorithm classifies an incoming packet into a flow and drops it stochastically according to the queue length and the fair bandwidth share ...
متن کاملPriority-Based Model of Subchannel Allocation in WiMAX Downlink
Priority-based model of subchannel allocation in WiMAX downlink is presented, which is based on solution of the optimization problem associated with maximizing the lower weighted bound of allocated bandwidth for each subscriber station according to its quality of service requirements for access rate and priority. Numerical research of model showed that increasing of the bandwidth requirements o...
متن کاملAn Adaptive Scheduling Scheme for Fair Bandwidth Allocation
Class-based service differentiation is provided in DiffServ networks. However, this differentiation will be disordered under dynamic traffic loads due to the fixed weighted scheduling. An adaptive weighted scheduling scheme is proposed in this paper to achieve fair bandwidth allocation among different service classes. In this scheme, the number of active flows and the subscribed bandwidth are e...
