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 ...
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 ...
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, ...
Service differentiation in multirate wireless networks with weighted round-robin scheduling and ARQ-based error control
(2006-02-28)
The radio link-level delay statistics in a wireless network using adaptive modulation and coding (AMC), weighted round-robin (WRR) scheduling, and automatic repeat request-based error control is analyzed in this letter. ...
Analysis of TCP performance under joint rate and power adaptation in cellular WCDMA networks
(2004-05-31)
To improve the spectral efficiency while meeting the radio link level quality of service requirements such as the bit-error-rate (BER) requirements for the different wireless services, transmission rate and power corresponding ...
Adaptive fair subcarrier/rate allocation in multirate OFDMA networks: Radio link level queuing performance analysis
(2006-11-30)
This paper presents a semi-analytical methodology for radio link level performance analysis in a multirate "orthogonal frequency-division multiple-access" (OFDMA) network with adaptive fair rate allocation. Multirate ...
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 forward link transmission using high-order modulation and multicode formats in cellular WCDMA networks
(2005-09-30)
This paper addresses. the problem of dynamic rate and power adaptation for forward link data transmission using high-order modulation and multicode formats in cellular wideband code division multiple access (WCDMA) networks. ...
On adaptive hybrid error control in wireless networks using reed-solomon codes
(2005-05-31)
This letter models and analyzes an adaptive radio link level error control protocol using Reed-Solomon codes for wireless networks. Results show that the proposed dynamic rate adaptive strategy provides a much improved ...
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 ...
