Queue-aware uplink bandwidth allocation and rate control for polling service in IEEE 802.16 broadband wireless networks
(2006-06-30)
IEEE 802.16 standard defines the air interface specifications for broadband access in wireless metropolitan area networks. Although the medium access control signaling has been well-defined in the IEEE 802.16 specifications, ...
Call admission control for QoS provisioning in 4G wireless networks: Issues and approaches
(2005-10-31)
This article presents a survey on the issues and the approaches related to designing call admission control schemes for fourth-generation wireless systems. We review the state of the art of CAC algorithms used in the ...
A queuing-theoretic and optimization-based model for radio resource management in IEEE 802.16 broadband wireless networks
(2006-11-30)
We present a queuing-theoretic and optimization-based model for radio resource management in IEEE 802.16-based multiservice broadband wireless access (BWA) networks considering both packet-level and connection-level ...
Link-level traffic scheduling for providing predictive QoS in wireless multimedia networks
(2004-02-29)
A set of centralized burst-level cell scheduling schemes, namely, First Come First Served with Frame Reservation (FCFS-FR), FCFR-FR+, Earliest Deadline First with Frame Reservation (EDF-FR), EDF-FR+, and Multitraffic Dynamic ...
Delay statistics and throughput performance for multi-rate wireless networks under multiuser diversity
(2006-11-30)
An analytical framework for radio link level performance evaluation under scheduling and automatic repeat request (ARQ)-based error, control in a multi-rate wireless network is presented. The multi-rate transmission is ...
Dynamic rate and power adaptation for provisioning class-based QoS in cellular multirate WCDMA systems
(2004-09-30)
This paper addresses the problem of dynamic link adaptation under multiple quality-of-service (QoS) constraints in cellular wideband code-division multiple-access (WCDMA) systems. A novel dynamic joint rate and power ...
QoS and energy trade off in distributed energy-limited mesh/relay networks: A queuing analysis
(2006-06-30)
In a distributed multihop mesh/relay network (e.g., wireless ad hoc/sensor network, cellular multihop network), each node acts as a relay node to forward data packets from other nodes. These nodes are often energy-limited ...
Call-level and packet-level quality of service and user utility in rate-adaptive cellular CDMA networks: A queuing analysis
(2006-12-31)
A queuing analytical model is presented to evaluate call-level and packet-level quality of service (QoS) metrics in the uplink of a voice/data cellular code division multiple access ( CDMA) network. In this model, a ...
Radio link level performance evaluation in wireless networks using multi-rate transmission with ARQ-based error control
(2006-10-31)
This letter presents an analytical framework for radio link level performance evaluation in a wireless network using adaptive modulation and coding (AMC) and automatic repeat request (ARQ)-based error control. Both the ...
Downlink joint rate and power allocation in cellular multirate WCDMA systems
(2003-01-31)
This paper proposes a novel dynamic joint rate, and power control procedure for, downlink data transmission in a multicell variable spreading factor wideband code-division multiple-access (WCUMA), system where the different ...
