Tracking the Empirical Distribution of a Markov-modulated Duplication-Deletion Random Graph
Maziyar Hamdi, Vikram Krishnamurthy, George Yin
This paper considers a Markov-modulated duplication-deletion random graph where at each time instant, one node can either join or leave the network; the probabilities of joining or…
QoS Provisioning for Multimedia Transmission in Cognitive Radio Networks
F. Richard Yu, Bo Sun, Vikram Krishnamurthy +1
In cognitive radio (CR) networks, the perceived reduction of application layer quality of service (QoS), such as multimedia distortion, by secondary users may impede the success of…
Bayesian Sequential Detection with Phase-Distributed Change Time and Nonlinear Penalty -- A POMDP Approach
Vikram Krishnamurthy
We show that the optimal decision policy for several types of Bayesian sequential detection problems has a threshold switching curve structure on the space of posterior distributio…
Quickest Time Herding and Detection for Optimal Social Learning
Vikram Krishnamurthy
This paper considers social learning amongst rational agents (for example, sensors in a network). We consider three models of social learning in increasing order of sophistication.…
