Appropriate bandwidth allocation is an important issue to benefit the long Term Evolution (LTE) networks performance. Single-carrier FDMA (SC-FDMA) multiple access scheme has been chosen for the 3GPP LTE uplink scheduling. However, it requires that all the sub carriers allocated to a single user must be in contiguous frequency band within each time slot. This constraint limits the scheduling flexibility...
To compensate for the adverse effects caused by radio link in worldwide interoperability for Microwave Access (WiMAX) networks, many radio resource management approaches have been present to assign orthogonal frequency division multiplexing access slots for seeking better performance. However, no WiMAX standards for optimal slot allocation have been defined. In this study, a new uplink bandwidth allocation...
Decision making is the hot topic in business management. Recently, there have been investigations in Call Admission Control (CAC) to handle the handover events in wireless network environments. Wireless networks have been seen to support different handoff mechanisms, in which the user can switch from one wireless network to another such as from IEEE 802.11 to IEEE 802.16. Many wireless standards,...
This paper proposes a novel radio resource management scheme in the link adaptive WiMAX network and the hierarchical priority-queuing with weighted round-robin (HPWRR) scheduling algorithm for different traffic services. The radio resource management scheme can re-assign the burst profile and dynamically adjust the allocated bandwidth to the SSs to improve the resource utilization. Then, the HPWRR...
A lot of wireless standards are proposed to satisfy diversified requirements for mobile users such as IEEE 802.16 and IEEE 802.11. It is feasible to integrate heterogeneous networks to provide complete wireless services. Several strategies were proposed to realize seamless handoff in the heterogeneous networks; however, most of them were only designed to meet system performance or individual QoS requirements...
