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 ... -
Dynamic network provisioning for time-varying traffic
Sharma, V.; Kar, K.; La, R.; Tassiulas, L. (2007)In this paper, we address the question of dynamic network provisioning for time-varying traffic rates, with the objective of maximizing the system throughput. We assume that the network is capable of providing bandwidth ... -
Layered multicast rate control based on lagrangian relaxation and dynamic programming
Kar, K.; Tassiulas, L. (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 ... -
Layered multicast rate control based on Lagrangian relaxation and dynamic programming
Kar, K.; Tassiulas, L. (2006)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 ... -
Scheduling Algorithms for Optical Packet Fabrics
Kar, K.; Stiliadis, D.; Lakshman, T. V.; Tassiulas, L. (2003)Utilizing optical technologies to build packet fabrics for high-capacity switches and routers has several advantages in terms of scalability, power consumption, and cost. However, several technology related problems have ...
