This paper proposes a new scheduling algorithm for IEEE 802.16-2005 Broadband Wireless Metropolitan Area Networks in TDD mode. The proposed algorithm focuses on solving the problem of handling high priority traffic in congested networks while minimizing starvation conditions for other served classes. In this work, a detailed simulation study is carried out for the proposed scheduling algorithm as...

Providing guaranteed quality-of-service (QoS) for resource-hungry multimedia applications over wireless fading channels is challenging. Traditional layered architecture fails miserably in providing the QoS requirement of high throughput, low latency demand of these kinds of applications in wireless mobile networks. Cross-layer design approaches are critical for efficient utilization of the scarce...
In this paper, we consider an uplink multiservice networks employing Orthogonal Frequency Division Multiple Access (OFDMA) for WiMAX networks. Since the OFDMA physical resource available for scheduling is frame by frame, the uplink scheduler located at base station (BS) must efficiently allocate available resources to the subscriber stations (SSs) in response to constant or bursty data traffic on...
Being a new feature of next generation of wireless networks, MMR (mobile multi-hop relay) is proposed for the purpose of coverage extension and throughput enhancement in IMT-Advanced, IEEE 802.16j/m. Besides, with the help of relay, the system energy consumption could be well saved. In this paper, an energy saving scheduling scheme is proposed for OFDMA based two-hop relay systems. The novel scheme...
The IEEE 802.16 standard is expected to become a successful broadband wireless access solution, especially thanks to its ablility to provide high data rates, to differentiate services, and thanks to its interoperability, as promoted by the worldwide interoperability for microwave access (WiMAX) organization. We consider in this paper an Orthogonal frequency division multiple access (OFDMA)-based 802...
