“…The authors in (Msadaa et al, 2010) also classify the algorithms into three categories: algorithms based on packet queuing, algorithms based on optimization strategies and crosslayer algorithms. The scheduling strategy based on queuing packet has the same characteristics of the algorithms developed for wired networks.…”

“…This stage can be characterized according to the number of scheduling levels. Typically, an one-level structure, with a single queuing discipline that attends all scheduling services, is used [7]. However, such structure is usually devoted to a specific problem and ignores the assembly of the OFDMA frame.…”

Mobile devices and real-time applications are increasingly demanding metropolitan network access with guaranteed quality of service. Current research points to the need of two main stages to provide quality of service in OFDMAbased WiMAX networks. These stages, called scheduling and allocation are deeply investigated on the literature. However, details on the integration of these mechanisms are not provided. Therefore, in this paper, we propose the integration of scheduling and allocation through a threshold criteria that considers the diversity of the traffic, limiting the amount of data and mapping overhead sent to allocation. The results show that our proposal is fundamental to integrate scheduling and allocation and is able to improve quality of service parameters, such as data allocation and delay.

“…The algorithm calculates a deadline for each rtPS connection (line 10) as defined in expression (1). After this, it sorts the rtPS connections by the lowest deadline (lines [13][14][15][16][17][18][19]. Thus, it is possible to minimize the delay existent at the access network by the use of various MCSs.…”

In this article, an adaptive scheduling packets algorithm for the uplink traffic in WiMAX networks is proposed. The proposed algorithm is designed to be completely dynamic, mainly in networks that use various modulation and coding schemes (MCSs). Using a cross-layer approach and the states of the uplink virtual queues in the base station, it was defined a new deadlines-based scheme, aiming at limiting the maximum delay to the real-time applications. Moreover, a method which interacts with the polling mechanisms of the base station was developed. This method controls the periodicity of sending unicast polling to the real-time and non-real-time service classes, in accordance with the quality of service requirements of the applications. The proposed algorithm was evaluated by means of modeling and simulation in environments where various MCSs were used and also in an environment where only one type of MCS was used. The simulations showed satisfactory results in both environments.
