On Systemic Risk in the Cloud Computing Model

October 23, 2014
Author(s)
Vladimir V. Marbukh
The major benefits of the emerging cloud computing infrastructure include elimination of the fixed cost and reduction in the marginal cost for the users due to the economy of scale and dynamic resource sharing. This paper argues that these unquestionable

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

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

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

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

Distributed Deployment Algorithms for Improved Coverage in Mobile Sensor Networks

September 28, 2011
Author(s)
Vladimir V. Marbukh, Kamran Sayrafian, Hamid Mahboubi, Kaveh Moezzi, Amir G. Aghdam
In this paper, various sensor deployment strategies are studied for effective coverage in wireless sensor networks. In the proposed algorithms, each sensor discovers the coverage holes within its Voronoi polygons, and then moves in a proper direction to

Towards Evolutionary-Pricing Framework for Mobile Sensor Network Self-organization

July 18, 2010
Author(s)
Vladimir V. Marbukh, Kamran Sayrafian, Hamid Mahboubi, Ahmadreza Momeni, Amir G. Aghdam
This paper reports on work in progress on developing a unified co-evolutionary/pricing framework for Mobile Sensor Networks (MSN) self-organization. MSN self-organization involves cooperative sensor positioning and formation of a multi-hop Mobile Ad-hoc

Optimal Target Tracking Strategy with Controlled Node Mobility in Mobile Sensor Networks

June 30, 2010
Author(s)
Kamran Sayrafian, Vladimir V. Marbukh, Hamid Mahboubi, Ahmadreza Momeni, Amir G. Aghdam
This paper is concerned with target tracking using a network of collaborative 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 prescribed
