Handling asymmetry in gain in directional antenna equipped ad hoc networks
(2005)
The deployment of traditional higher layer protocols (especially the IEEE 802.11 MAC protocol at the MAC layer) with directional antennae could lead to problems from an increased number of collisions; this effect is primarily ...
Distributed dynamic scheduling for end-to-end rate guarantees in wireless ad hoc networks
(2005)
We present a framework for the provision of deterministic end-to-end bandwidth guarantees in wireless ad hoc networks. Guided by a set of local feasibility conditions, multi-hop sessions are dynamically offered allocations, ...
Maxmin fair scheduling in wireless ad hoc networks
(2005)
We investigate from an algorithmic perspective the maxmin fair allocation of bandwidth in wireless ad hoc networks. We formalize the maxmin fair objective under wireless scheduling constraints, and present a necessary and ...
Providing quality of service guarantees in wireless LANs compliant with 802.11e
(2005)
Quality of Service (QoS) support is a key attribute of a broadband communication system and is missing in 802.11-based wireless LANs. Recognizing the need, Task Group e (TGe) is work-ins! towards 802.11e, an evolution of ...
Fair distributed congestion control in multirate multicast networks
(2005)
We study fairness of resource allocation in multirate, multicast networks. In multirate networks, different receivers of the same multicast session can receive service at different rates. We develop a mathematical framework ...
End-to-end bandwidth guarantees through fair local spectrum share in wireless ad-hoc networks
(2005)
Sharing the common spectrum among the links in a vicinity is a fundamental problem in wireless ad-hoc networks. Lately, some scheduling approaches have been proposed that guarantee fair share of bandwidth among the links. ...
A class of multi-carrier CDMA access methods for wide-bandwidth wireless channels
(2005)
In this article we describe and evaluate a general class of synchronous multi-carrier CDMA methods. In the proposed methods each accessing user is encoded by a Hadamard sequence and a multi-carrier (MC) encoder. The ...
Back pressure based multicast scheduling for fair bandwidth allocation
(2005)
We study the fair allocation of bandwidth in multicast networks with multirate capabilities. In multirate transmission, each source encodes its signal in layers. The lowest layer contains the most important information and ...
Distributed topology construction of Bluetooth wireless personal area networks
(2005)
Bluetooth, a wireless technology based on a frequency-hopping physical layer, enables portable devices to form short-range wireless ad hoc networks. Bluetooth hosts are not able to communicate unless they have previously ...
Packetostatics: Deployment of massively dense sensor networks as an electrostatics problem
(2005)
We investigate the spatial distribution of wireless nodes that can transport a given volume of traffic in a sensor network, while requiring the minimum number of wireless nodes. The traffic is created at a spatially ...
