Achieving proportional fairness using local information in Aloha networks
Kar, K.; Sarkar, S.; Tassiulas, L. (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 ... -
Back pressure based multicast scheduling for fair bandwidth allocation
Sarkar, S.; Tassiulas, L. (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 ... -
End-to-end bandwidth guarantees through fair local spectrum share in wireless ad-hoc networks
Sarkar, S.; Tassiulas, L. (2003)Sharing the locally common spectrum among the links of the same vicinity is a fundamental problem in wire-less ad-hoc networks. Lately some scheduling approaches have been proposed that guarantee fair share of the bandwidth ... -
End-to-end bandwidth guarantees through fair local spectrum share in wireless ad-hoc networks
Sarkar, S.; Tassiulas, L. (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. ... -
Fair distributed congestion control in multirate multicast networks
Sarkar, S.; Tassiulas, L. (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 ... -
A fair scheduling policy for wireless channels with intermittent connectivity
Aaram, A.; Khouzani, M. H. R.; Sarkar, S.; Tassiulas, L. (2008)We consider a system of parallel queues with the constraint that only one queue can be served at a time. Each queue can be served through a wireless channel with intermittent connectivity. We propose a policy which serves ... -
Maxmin fair scheduling in wireless ad hoc networks
Tassiulas, L.; Sarkar, S. (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 ...
