Inter-BAN Interference Mitigation: A Correlated Equilibrium Perspective

June 13, 2014

Author(s)

Vladimir Marbukh, Kamran Sayrafian, Martina Barbi, Mehdi Alasti

A Body Area Network (BAN) is a wireless network of wearable or implantable computing devices. A BAN typically consists of several miniaturized radio-enabled body sensor/actuator that communicate with a single coordinator. Medical applications usually

Distributed Deployment Algorithms for Improved Coverage in a Network of Wireless Mobile Sensors

February 1, 2014

Author(s)

Kamran Sayrafian, Vladimir V. Marbukh, Hamid Mahboubi, Kaveh Moezzi, Amir Aghdam

In this paper, sensor deployment strategies are developed for effective coverage in wireless sensor networks. In the proposed algorithms, the sensors find coverage holes within the corresponding Voronoi polygons, and then move in a proper direction to

Link Layer Adaptation in Body Area Networks: Balancing Reliability and Longevity

September 8, 2013

Congestion Due to Random Walk Routing

August 31, 2013

Author(s)

Vladimir V. Marbukh, Iraj Saniee, Onuttom Narayan

In this paper we derive an analytical expression for the mean load at each node of an arbitrary undirected graph for the uniform multicommodity flow problem under random walk routing. We show the mean load is linearly dependent on the nodal degree with a

Perron-Frobenius Measure of Systemic Risk of Cascading Overload in Complex Clouds: Work in Progress

May 27, 2013

Author(s)

Vladimir V. Marbukh

Dynamic resource sharing has both positive and negative effects on the system performance. Current research mostly concentrates on the positive effect resulting from the statistical multiplexing gain. However, the negative effect resulting from the

A Game-Theoretic Framework for Network Security Vulnerability Assessment and Mitigation

November 5, 2012

Author(s)

Assane Gueye, Vladimir V. Marbukh

In this paper we propose and discuss a game-theoretic framework for (a) evaluating security vulnerability, (b) quantifying the corresponding Pareto optimal vulnerability/cost tradeo®, and (c) identifying the optimal operating point on this Pareto optimal

Maximum Life Span Strategy for Target Tracking in Mobile Sensor Networks

June 29, 2012

Author(s)

Vladimir V. Marbukh, Kamran Sayrafian, Hamid Mahboubi, Amir G. Aghdam, Walid Masoudimansour

In this paper, an energy-efficient technique is proposed for tracking a target in a field using a network of mobile sensors while maximizing the life span of the network. The most important energy consumption sources in a mobile sensor network (MSN) are

Towards a Metric for Communication Network Vulnerability to Attacks: A Game Theoretic Approach

May 25, 2012

Author(s)

Assane Gueye, Vladimir V. Marbukh, Jean C. Walrand

In this paper, we propose a quantification of the vulnerability of a communication network when links are subject to failures due to the actions of a strategic adversary. We model the adversarial nature of the problem as a 2-player game between an attacker

Systemic Risks/Benefits of Selfish Network Operations & Management in Dynamic Environment

April 16, 2012

Author(s)

Vladimir V. Marbukh

Allowing selfish agents to acquire and exploit system information has both positive and negative effects on the overall performance of resource allocation systems. The positive effect results from reduction in the uncertainty inherently present in large

Towards Modeling Effect of Packet-level TCP Dynamics on Internet Operations and Management

April 16, 2012

Author(s)

Vladimir V. Marbukh

This paper reports on work in progress on modeling of the effect of packet-level TCP congestion avoidance dynamics on flow-level Internet performance and management including buffer sizing under arriving/departing flows. The proposed model accounts for the

An Efficient Target Monitoring Scheme with Controlled Node Mobility for Sensor Networks

November 3, 2011

Author(s)

Vladimir V. Marbukh, Kamran Sayrafian, Hamid Mahboubi, Ahmadreza Momeni, Amir G. Aghdam

This paper is concerned with target monitoring using a network of collaborative mobile sensors. The objective is to compute (online) the desired sensing and communication radii of sensors as well as their location at each time instant, such that a set of

A Mathematical Model of Joint Congestion Control and Routing in Multisource Networks

September 28, 2011

Author(s)

Fern Y. Hunt, Vladimir V. Marbukh, Yi Wang

In this paper we study a model of joint congestion control and routing in a ring of network sources with a single destination at the center. A utility maximization problem subject to routing constraints is posed and equations for its solution are presented
