On optimal monitor placement for localizing node failures via network tomography
We investigate the problem of placing monitors to localize node failures in a communication network from binary states (normal/failed) of end-to-end paths, under the assumption th...

Dynamic service migration and workload scheduling in edge-clouds
Edge-clouds provide a promising new approach to significantly reduce network operational costs by moving computation closer to the edge. A key challenge in such systems is to dec...

Construction of Markov chains for discrete time MAP/PH/K queues
Two GI/M/1 type Markov chains associated with the queue length are often used in analyzing the discrete time MAP/PH/K queue. The first Markov chain is introduced by tracking servic...

Greening multi-tenant data center demand response
Data centers have emerged as promising resources for demand response, particularly for emergency demand response (EDR), which saves the power grid from incurring blackouts during ...

Queueing analysis of peer-to-peer swarms: Stationary distributions and their scaling limits
In this paper we analyze the dynamics of a P2P file exchange swarm from a queueing standpoint. In such systems, the service rate a peer receives depends on one mostly fixed comp...

A discrete-time queue with customers with geometric deadlines
This paper studies a discrete-time queueing system where each customer has a maximum allowed sojourn time in the system, referred to as the “deadline” of the customer. More sp...

On optimal policies for energy-aware servers
As energy costs and energy used by server farms increase, so does the desire to implement energy-aware policies. Although under some metrics, optimal policies for single as well a...

Characterizing the impact of the workload on the value of dynamic resizing in data centers
Energy consumption imposes a significant cost for data centers; yet much of that energy is used to maintain excess service capacity during periods of predictably low load. Result...

RECAST: Telling apart social and random relationships in dynamic networks
In this paper, we argue that the ability to accurately spot random and social relationships in dynamic networks is essential to network applications that rely on human routines, s...
