How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Quality of information (QoI) provides a context-dependent measure of the utility that a network delivers to its users by incorporating non-traditional information attributes. Quickly and easily predicting performance and limitations of a network using QoI metrics is a valuable tool for network design. Even more useful is an understanding of how net...
Article
We present a framework and a set of algorithms for determining faults in networks when large scale outages occur. The design principles of our algorithm, netCSI, are motivated by the fact that failures are geographically clustered in such cases. We address the challenge of determining faults with incomplete symptom information due to a limited numb...
Article
Backpressure Routing is a cross-layer control algorithm that makes decisions on routing and resource allocation in mobile ad hoc networks using network state information like queue backlog values and current available channel rates. While it is desirable because of its provable performance guarantees, including providing optimal throughput, the rea...

In many deployments of wireless sensor networks (WSNs), the primary goal is to collect and deliver data from many nodes to a data sink. This goal must be met while considering limited resources, such as battery life, in the wireless nodes. In this work, we propose considering the content of generated data to make intelligent data and node selection...
Article
We consider a discrete time queueing system where a controller makes a 2-stage decision every slot. The decision at the first stage reveals a hidden source of randomness with a control-dependent (but unknown) probability distribution. The decision at the second stage generates an attribute vector that depends on this revealed randomness. The goal i...

The freedom and flexibility of wireless Mobile Ad-hoc Networks (MANETs) that make them extremely desirable for many military, emergency, and sensor network applications also present challenges for multiple layers in the network stack. Max-weight scheduling, also known as backpressure routing, is a cross-layer control algorithm that is well-known to...

Article
In this paper, we review some security con-cerns of network utility maximization (NUM) based net-works. Nodes in NUM based networks rely on the ex-change of status messages to converge on optimal parame-ters for the network. We address concerns unique to NUM based networks, specifically focusing on denial of service (DoS) attacks. Through use of si...
