Network Provisioning as a Game Against Nature

May 1, 2003

Author(s)

Vladimir V. Marbukh

Traditional approaches to network provisioning assume availability of the reliable estimates for the expected demands. This assumption, however, oversimplifies many practical situations when some incomplete information on the expected demands is available

On Shortest Random Walks under Adversarial Uncertainty

May 1, 2003

Author(s)

Vladimir V. Marbukh

Finding shortest feasible paths in a weighted graph has numerous applications including admission and routing in communication networks. This paper discusses a game theoretic framework intended to incorporate a concept of path stability into the process of

A Cognitive Framework for Performance/Resilience Optimized Multipath Routing in Networks with Unstable Topologies

March 1, 2003

Author(s)

Vladimir V. Marbukh

This paper proposes a framework for optimized multipath routing in a wireless network with frequently changing topology. The topology changes may be due to node mobility in mobile ad hoc networks, or limited node reliability and power supply in sensor

QoS Routing Under Adversarial Binary Uncertainty

April 1, 2002

Author(s)

Vladimir V. Marbukh

A cost-based admission control and routing scheme admits an arriving request on the minimum cost route if this cost does not exceed the cost of the request, and rejects the request otherwise. Cost based strategies naturally arise as a result of

A Framework for Performance Evaluation and Optimization of an Emerging Multimedia DS-CDMA Network

July 10, 2001

Author(s)

Vladimir Marbukh, David H. Su

This paper proposes a framework for performance evaluation md optimization of an emerging multimedia, packet Direct-Sequence Code Division Multiple Access (DS-CDMA) network with a wide range of Quality of Service (QoS) requirements on losses and delays

Network Management Under Incomplete Information on the Operational Environment

November 1, 2000

Author(s)

Vladimir V. Marbukh

This paper proposes an approach to network management under incomplete information on the operational environment. The approach employs a combination of the minimax and Bayes' methodologies for making network management decisions under uncertainty. As an

A Queueing Model of a Spread Spectrum Multiple Access

June 1, 1999

Author(s)

Vladimir V. Marbukh, Nader Moayeri

We propose a queueing model of the reverse link from mobiles to the base station in a single cell of a cellular DS-CDMA system. Approximation of independent queues leads to a non-linear fixed point equation that describes globally or locally stable system

A Framework for Throughput and Stability Analysis of a DS-CDMA Network

May 17, 1999

Author(s)

Vladimir V. Marbukh, Nader Moayeri

We propose a framework for throughput and stability analysis of a Direct Sequence Code Division Multiple Access (DS-CDMA) network. Given chip rate, processing gains, packet structure, coding scheme, and the characteristics of the wireless channel, we

Towards Cross-Layer Optimization of a Wireless Network for Diverse Rate and Delay Requirements

Author(s)

Vladimir V. Marbukh

This paper extends the conventional link-centric aggregate utility maximization framework to a situation of users (applications) with diverse delay as well as rate requirements. Assuming that user utility is a function of the average transmission rate as
