Caching under Content Freshness Constraints
Pawan Poojary, Sharayu Moharir, Krishna Jagannathan
Several real-time delay-sensitive applications pose varying degrees of freshness demands on the requested content. The performance of cache replacement policies that are agnostic t…
Efficient CSMA using Regional Free Energy Approximations
Peruru Subrahmanya Swamy, Venkata Pavan Kumar Bellam, Radha Krishna Ganti +1
CSMA (Carrier Sense Multiple Access) algorithms based on Gibbs sampling can achieve throughput optimality if certain parameters called the fugacities are appropriately chosen. Howe…
Right buffer sizing matters: some dynamical and statistical studies on Compound TCP
Debayani Ghosh, Krishna Jagannathan, Gaurav Raina
Motivated by recent concerns that queuing delays in the Internet are on the rise, we conduct a performance evaluation of Compound TCP (C-TCP) in two topologies: a single bottleneck…
Spatial CSMA: A Distributed Scheduling Algorithm for the SIR Model with Time-varying Channels
Peruru Subrahmanya Swamy, Radha Krishna Ganti, Krishna Jagannathan
Recent work has shown that adaptive CSMA algorithms can achieve throughput optimality. However, these adaptive CSMA algorithms assume a rather simplistic model for the wireless med…
Queue Length Asymptotics for Generalized Max-Weight Scheduling in the presence of Heavy-Tailed Traffic
Krishna Jagannathan, Mihalis Markakis, Eytan Modiano +1
We investigate the asymptotic behavior of the steady-state queue length distribution under generalized max-weight scheduling in the presence of heavy-tailed traffic. We consider a…
