A Dynamic Programming Approach For Routing In Wireless Mesh Networks, Jorge Crichigno, Joud Khoury, Min-Yo Wu, Wei Shu Aug 2008

A Dynamic Programming Approach For Routing In Wireless Mesh Networks, Jorge Crichigno, Joud Khoury, Min-Yo Wu, Wei Shu

Electrical & Computer Engineering Technical Reports

The routing problem in Wireless Mesh Networks (WMNs) is concerned with finding good' source destination paths. It generally faces multiple objectives to be optimized, such as i) path capacity, which accounts for the bits per second (bps) that can be sent along the path connecting the source to the destination node, and ii) end-to-end delay. This paper presents the Mesh Routing Algorithm (MRA), a dynamic programming approach for computing high-capacity paths while simultaneously bounding the end-to-end delay. The proposed algorithm also provides the option for locating multiple link-disjoint paths, such that the amount of traffic through each path is proportional …


A Model Of Human Categorization And Similarity Based Upon Category Theory, Michael Healy, Thomas Caudell, Timothy Goldsmith Jul 2008

A Model Of Human Categorization And Similarity Based Upon Category Theory, Michael Healy, Thomas Caudell, Timothy Goldsmith

Electrical & Computer Engineering Technical Reports

Categorization and the judgement of similarity are fundamental in cognition. We propose that these and other activities are based upon an underlying structure of knowledge, or concept representation, in the brain. Further, we propose that this structure can be represented mathematically in a declarative form via category theory, the mathematical theory of structure. We test the resulting mathematical model in an experiment in which human subjects provide judgements of similarity for pairs of line drawings using a numerical scale to represent degrees of similarity. The resulting numerical similarities are compared with those derived from the category-theoretic model by comparing diagrams. …


Towards A Taxonomy Of Inter-Network Architectures, Joud Khoury, Chaouki Abdallah Jun 2008

Towards A Taxonomy Of Inter-Network Architectures, Joud Khoury, Chaouki Abdallah

Electrical & Computer Engineering Technical Reports

Over the past decade, research on network architecture design has intensified. However, contributions to the field have mainly been idiosyncratic and architectural descriptions remain idiomatic. This state of affairs has led to the emergence of a large body of network architecture proposals with no clear indication of their compatibility points, their cross similarities, and their differences. Thus, a taxonomy of network architectures that provides a framework for better understanding, organizing, and thinking about the complex architecture design space would be a timely contribution. This paper presents a first step in that direction by attempting a classification based on the architecture's …


Towards Formalizing Network Architectural Descriptions, Joud Khoury, Chaouki Abdallah, Gregory Heileman Mar 2008

Towards Formalizing Network Architectural Descriptions, Joud Khoury, Chaouki Abdallah, Gregory Heileman

Electrical & Computer Engineering Technical Reports

Despite the rich literature on network architecture and communication system design, the current practice of describing architectures remains informal and idiosyncratic. Such practice has evolved based on idiomatic terminology and hence, it is failing to provide a formal framework for representing and for reasoning about network architectures. This state of affairs has led to the overloading of architectural terms, and to the emergence of a large body of network architecture proposals with no clear indication of the their cross similarities, their compatibility points, their unique properties, and their architectural performance and soundness. Formalizing network architectural descriptions is therefore a timely …
