Distributed on-line schedule adaptation for balanced slot allocation in wireless ad hoc networks
(2004)
We propose an algorithm for design and on the fly modification of the schedule of a wireless ad hoc network for provision of fair service guarantees under topological changes. The primary objective is to derive a distributed ...
On optimal cooperative route caching in large, memory-limited wireless ad hoc networks
(2004)
Caching is a popular mechanism for enhancing performance in various layers and applications of computer networking. We introduce both a model and algorithms for caching routing information in large, memory-limited wireless ...
Layered multicast rate control based on lagrangian relaxation and dynamic programming
(2004)
In this paper, we address the rate control problem for layered multicast traffic, with the objective of solving a generalized throughput/fairness objective. Our approach is based on a combination of lagrangian relaxation ...
Achieving proportional fairness using local information in Aloha networks
(2004)
We address the problem of attaining proportionally fair rates using Aloha protocols at the medium access layer. We consider a wireless network where all nodes need not be in transmission ranges of each other. We show how ...
Asynchronous TDMA ad hoc networks: scheduling and performance
(2004)
A common assumption of time division multiple access (TDMA)-based wireless ad hoc networks is the existence of network-wide slot synchronization. Such a mechanism is difficult to support in practice. In asynchronous TDMA ...
Adaptive channel allocation in OFDM/SDMA wireless LANs with limited transceiver resources
(2004)
Smart antennas increase capacity of wireless systems by allowing channel reuse by several users in the same cell through space division multiple access (SDMA). Orthogonal Frequency Division Multiplexing (OFDM) creates ...
Exploiting wireless channel, state information for throughput maximization
(2004)
We consider the problem of scheduling packets over channels with time-varying quality. This problem has received a lot of attention lately in the context of devising methods for providing quality of service in wireless ...
Maximum lifetime routing in wireless sensor networks
(2004)
A routing problem in static wireless ad hoc networks is considered as it arises in a rapidly deployed, sensor based, monitoring system known as the wireless sensor network. Information obtained by the monitoring nodes needs ...
