Economics of Networked Infrastructures at the Edge of Undesirable Contagion: A Case of SIS Infection

July 9, 2018

Author(s)

Vladimir V. Marbukh

This paper reports on managing systemic risk of undesirable contagion in a networked system in a practically important case of high losses due to contagion. In this case, both socially optimal as well as selfish investments in the risk mitigation keep the

Towards Efficient Offloading in Fog/Edge Computing by Approximating Effect of Externalities

July 9, 2018

Author(s)

Vladimir V. Marbukh

Fog/Edge computing is an emerging architecture, which extends the Cloud computing paradigm to the edge of the network, enabling new applications and services, including Internet of Things (IoT). End devices have certain computation tasks, which can be

Towards Managing Age of Network State Information in Challenged Networks

July 8, 2018

Author(s)

Vladimir V. Marbukh

Age of Information (AoI) is a recently introduced metric for freshness of the real-time information, which requires frequent updates. This paper argues that AoI is useful not only for real-time network applications, but also for network state information

Fragility Risks of Low Latency Dynamic Queuing in Large-Scale Clouds: Complex System Perspective

January 23, 2018

Author(s)

Vladimir V. Marbukh

Economic, reliability, and low latency benefits of cloud computing model are the result of high level of dynamic resource sharing, made possible by high degree of system interconnectivity. This paper suggests more nuanced view of the effect of

Regret Minimization Based Adaptation of the Energy Detection Threshold in Body Area Networks

August 24, 2017

Author(s)

Vladimir V. Marbukh, Kamran Sayrafian

IEEE802.15.6 is a radio interface standard for wireless connectivity of wearable and implantable sensors and actuators located inside or in close proximity to the human body i.e., Body Area Network (BAN). Medical applications impose stringent requirements

Systemic Risks in the Cloud Computing Model: Complex Systems Perspective

January 19, 2017

Author(s)

Vladimir V. Marbukh

This paper reports on quantification and management of inherent systemic risk/performance tradeoff in the cloud computing model. We view Cloud as a Complex System and associate the systemic risks with a possibility of system phase transition to the

Towards Cross-Layer Design of Communication Network for Smart Grid with Real-Time Pricing

December 12, 2016

Author(s)

Vladimir V. Marbukh

The efficiency of the emerging smart power grid infrastructure critically depends on the ability of the communication network to deliver real-time energy prices to the consumers. This papers contribution is twofold. First, it derives the relevant Quality

Towards Systemic Risk Aware Engineering of Large-Scale Networks: Complex Systems Perspective

December 8, 2016

Author(s)

Vladimir V. Marbukh

This paper proposes a framework for systemic risk aware engineering of large-scale networks. Economics drives two major evolutionary trends in networked system design/operation: (a) towards the boundary of the system capacity/operational region, where all

A Queue-Size & Channel Quality Based Adaptation of the Energy Detection Threshold in IEEE802.15.6 CSMA/CA

November 21, 2016

Author(s)

Vladimir V. Marbukh, Martina Barbi, Kamran Sayrafian, Mehdi Alasti

IEEE802.15.6 is a radio interface standard for a wireless connectivity of wearable and implantable sensors and actuators located inside or in close proximity to the human body i.e., Body Area Network (BAN). Medical applications impose stringent

Effect of Bounded Rationality on Tradeoff Between Systemic Risks & Economic Efficiency in Networks

August 11, 2016

Author(s)

Vladimir V. Marbukh

This paper discusses effect of bounded rationality on the systemic risks vs. economic performance tradeoff in large-scale networks operating under economic pressures. Existence of systemic risks in economically incentivized networked systems is

A Regret Matching Strategy Framework for Inter-BAN Interference Mitigation

February 4, 2016

Author(s)

Vladimir Marbukh, Kamran Sayrafian, Martina Barbi, Mehdi Alasti

A Body Area Network (BAN) is a radio standard for wireless connectivity of wearable and implantable sensors located inside or in close proximity to the human body. Medical and some other applications impose stringent constraints on battery powered BAN

Towards Unified Perron-Frobenius Framework for Managing Systemic Risk in Networked Systems

September 3, 2015

Author(s)

Vladimir V. Marbukh

Along with economic and convenience benefits, interconnectivity also brings potential risks and drawbacks. System designers and operators are faced with problem of balancing the relevant systemic risk/benefit tradeoffs. Assuming that system components are

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
