Radio resource allocation in WiMAX is the major functionality of radio resource management
(RRM) to support the Quality of Service (QoS) based on radio transmission characteristics in …

In this paper, a novel adaptive ant colony slot assignment (ACSA) algorithm including
construct solution and pheromone update is proposed to assign OFDMA-based radio …

Generally, slot allocation is followed by power allocation for sub-channels in that slot. The
power can be allocated equally to all sub-channels which an optimal power allocation over …

OFDMA (Orthogonal Frequency-Division Multiple Access) is one of the most important
technologies applied in Long Term Evolution (LTE) of wireless radio system [1]. In OFDMA …

IEEE 802.16 e based WiMAX networks promise a desirable available quality of service for
mobile users and scheduling algorithms provide the best effective use of network resources …

IEEE 802.16 standard defines the broadband wireless access specification for WiMAX
without any standardized schemes for resource allocation and scheduling, which has thus …

This paper proposes an optimized scheduling scheme in OFDMA‐based WiMax networks to
achieve both optimized system throughput and a complete QoS implementation for various …

Orthogonal frequency division multiple access (OFDMA), which is widely used in the
wireless sensor networks, allows different users to obtain different subcarriers according to …

In recent years, large usage of wireless networks puts forward challenge to the utilization of
spectrum resources, and it is significant to improve the spectrum utilization and the system …

Orthogonal frequency division multiple access (OFDMA) has been adopted as the core
physical layer access for a few broadband wireless access networks such as worldwide …
