—Scheduling algorithms are of utmost importance in WiMAX for efficient use of radio resources. A scheduling algorithm should take into account the WiMAX QoS classes and service requirements. It should also provide high throughput. In this paper, we propose a review of scheduling algorithms proposed for WiMAX. We focus on the real-time Polling Service (rtPS)(More)
In this paper, an evolution of the power control algorithm is proposed for the third-generation WCDMA system. The algorithm is based on a modification of the transmitted power update step size. Instead of the presently-suggested fixed value, the step size is modified dynamically in order to guarantee more adapted power variations. The proposed algorithm is(More)
In this paper, we consider header suppression and header compression in WiMAX/ IEEE 802.16 BWA (broadband wireless access) system. The data packet headers always carry some redundancy. In wireless systems such as WiMAX, it is important for radio resource use efficiency to reduce this redundancy. Both header suppression and then header compression have been(More)
Energy consumption of wireless networks is now a very important research topic and several research teams worldwide are proposing solutions for the so-called green wireless networks, i.e. energy-efficient wireless networks. Although the increase of this research activity is rather recent, a great number of research papers and collaborative projects exist(More)
—WiMAX/IEEE 802.16 system is a very open Broad-band Wireless Access (BWA) technology with different possible services. Pricing of WiMAX is an important topic with different optimization possibilities. In a previous paper, we investigated WiMAX pricing for real-time applications (Unsolicited Grant Service (UGS) and real-time Polling Service (rtPS) QoS(More)
