“…Since real time services need extra bandwidth for variable data changing rate, it increases the performance by reducing delay and loss rate. It has been proved that the scheduling algorithm that considered wireless link perform better than the algorithm that does not consider wireless link (Revankar et al, 2010). Chuang et al (2013) propose a QoS scheme based on Modified Deficit Round Robin (MDRR) of packet scheduling and Call Admission Control (CAC) with the channel condition for non-realtime service.…”

The objective of the broadband wireless technologies is to ensure the end to end Quality of Service (QoS) for service classes. Wimax is a revolution in wireless networks which could support real time multimedia services. In order to provide QoS support and efficient usage of system resources an intelligent scheduling algorithm is needed. The design of detailed scheduling algorithm is a major focus for researchers and service providers. In this study, a channel aware cross-layer scheduling algorithm for Wimax networks has been proposed. This scheme employs Signal to Noise Ratio (SNR) value which allocates bandwidth based on the information about the quality of the channel and service requirements of each connection. The proposed algorithm is described in detail and evaluated through series of simulation. The simulation results prove that the proposed algorithm reduces the packet loss rate and delay and thus improves throughput by 12.8%.

-In this paper, we present a new Petri Net (PN) approach to model the IEEE 802.16 MAC Protocol called Higher-Order Stochastic Reward Net (HOSRN) and through the application of the proposed rule. HOSRN is used as a modeling formalism as it readily captures the quality of service requirements of the traffic classes. We apply HOSRN to verify the effectiveness of QoS of the protocol using Reachability graph.

WiMAX networks are deployed for commercial use because of its nature high bandwidth. This requirement invokes the application level changes in QoS provisioning techniques. The objective of the broadband wireless technologies is to ensure the end to end Quality of Service (QoS) for the service classes. WiMAX is a revolution in wireless networks, which could support real time multimedia services. In order to provide QoS support and efficient usage of system resources an intelligent scheduling algorithm is needed. The design of the detailed scheduling algorithm is a major focus for researchers and service providers. In this study, a channel aware cross-layer scheduling algorithm for WiMAX networks has been proposed. This scheme employs the Signal to Noise Ratio (SNR) value, which allocates the bandwidth based on the information about the quality of the channel and the service requirements of each connection. The proposed algorithm is described in detail and evaluated, through a series of simulations. The QoS parameters of throughput, bandwidth efficiency and transmission efficiency have been measured in simulation.
