Fiber-wireless (FiWi) access mesh networks have been proposed as flexible and cost-effective solutions for future access networks. However, for FiWi access mesh networks to provide end-to-end QoS guarantees to its customers, efficient QoS routing schemes and scheduling policies become necessary. Here we provide a model, using repeated game theory, that creates ground for scheduling policies to be...
WiMAX is an advanced broadband wireless access technology that supports multimedia transmission. Here we propose a batch-arrival queueing model for evaluating WiMAX QoS-aware packet scheduling systems and obtaining packet loss rate (PLR), queueing delay (QD), and bandwidth utilization (BU) performance measures. These are used to solve a utilization optimization problem associated with QoS constraints...
Ethernet passive optical network (EPON) and worldwide interoperability for microwave access (WiMax) are two promising broadband access technologies for next-generation wired and wireless access network. The integrated architecture of complementary EPON and WiMax technologies combine the benefits of optical fiber capacity and wireless network mobility. In this paper, we propose a dynamic bandwidth...
In this paper, we propose a radio resource scheduling algorithm for a scheduler in IEEE 802.16 orthogonal frequency division multiple access (OFDMA) specification. The scheduler dynamically allocates slots considering wireless channel conditions of subscriber stations to improve radio resource utilization efficiency. The results show that with the proposed algorithm, smaller radio resources are used...
Call admission control (CAC) plays a critical role in the performance of the IEEE 802.16 mesh networks. The IEEE 802.16 standard does not specify any CAC mechanisms. In this paper, based on bandwidth estimation, we propose a call admission control scheme in IEEE 802.16 centralized scheduling mesh mode. The proposed scheme does the admission control function by using the characteristic defined in the...
