The IEEE 802.16 standard defines MAC and Physical layers for broadband wireless networks called WiMAX, however, it does not define the scheduling algorithm for the uplink and downlink traffic. In this paper, a predictive scheduling algorithm for uplink traffic in IEEE 802.16 networks is proposed. The proposed algorithm uses the cross-layer approach and is applied on the queue of the bandwidth requests...
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 have proposed an adaptive scheduling algorithm to suit group mobility scenarios in the mobile WiMAX. The QoS scheduling scheme aims to minimize the end-to-end delay for real-time traffic. IEEE 802.16e is a wireless broadband network standard aimed at providing robust, high data rate mobile communication. The issue of group mobility in mobile WiMAX networks has not been explored so...
In this paper, the optimal scheduling problem for ultrawideband (UWB) networks is formulated as a utility maximization problem, considering heterogeneous traffic characteristics and the fairness constraint, which is an NP-hard problem. The utility function, defined as the user satisfaction level with respect to the allocated bandwidth, takes the link distance as the input parameter that may be noisy...
