Scheduling in IEEE 802.16e mobile WiMAX networks: key issues and a survey
TL;DR: The goals of scheduling are to achieve the optimal usage of resources, to assure the QoS guarantees, to maximize goodput and to minimize power consumption while ensuring feasible algorithm complexity and system scalability.

Performance Evaluation of Cognitive Radios: Metrics, Utility Functions, and Methodology
TL;DR: This paper discusses the interrelationships among metrics, utility functions, cognitive engine algorithms, and achieved performance, as well as various testing scenarios and proposes the radio environment map-based scenario-driven testing (REM-SDT) for thorough performance evaluation of cognitive radios.

Convergence of ethernet PON and IEEE 802.16 broadband access networks and its QoS-aware dynamic bandwidth allocation scheme
TL;DR: A dynamic bandwidth allocation (DBA) scheme takes into consideration the specific features of the converged network to enable a smooth data transmission across optical and wireless networks, and an end-to-end differentiated service to user traffics of diverse QoS (Quality of Service) requirements.
Journal ArticleDOI
A Multihop Peer-Communication Protocol With Fairness Guarantee for IEEE 802.16-Based Vehicular Networks
TL;DR: The simulation results have shown that the proposed CEPEC protocol provides higher throughput with guaranteed fairness in multihop data delivery in vehicular networks when compared with the purely IEEE 802.16-based protocol.
Journal ArticleDOI
A performance study of uplink scheduling algorithms in point-to-multipoint WiMAX networks
TL;DR: A comprehensive performance study of scheduling algorithms in point-to-multipoint mode of OFDM-based WiMAX networks shows that none of the current algorithms is capable of effectively supporting all WiMAX classes of service.

Efficient fair queueing using deficit round-robin
M. Shreedhar,George Varghese +1 more
TL;DR: This paper describes a new approximation of fair queuing that achieves nearly perfect fairness in terms of throughput, requires only O(1) work to process a packet, and is simple enough to implement in hardware.

IEEE standard 802.16: a technical overview of the WirelessMAN/sup TM/ air interface for broadband wireless access
TL;DR: The technical medium access control and physical layer features of the IEEE standard 802.16, with its WirelessMAN/sup TM/ air interface, sets the stage for widespread and effective deployments worldwide.
Journal ArticleDOI
Broadband wireless access with WiMax/802.16: current performance benchmarks and future potential
TL;DR: This article presents the realistic attainable throughput and performance of expected WiMax compatible systems based on the 802.16d standard approved in June 2004 and suggests future enhancements to the standard that could at least quadruple the achievable data rate.
Journal ArticleDOI
MPEG-4 and H.263 video traces for network performance evaluation
TL;DR: A publicly available library of frame size traces of long MPEG-4 and H.263 encoded videos, generated at the Technical University Berlin are presented and a thorough statistical analysis of the traces are conducted.
Journal ArticleDOI
A model for generating on-off speech patterns in two-way conversation
TL;DR: A model that generates on-off speech patterns representative of those in experimental two-way telephone conversations that yields good fits to all events except “speech before interruption;” when an interruption occurs, a model speaker tends to interrupt the other's talkspurt later than a real speaker does.
