Topology of Urban Environments

چکیده
This paper introduces a practical approach to constructing a hybrid 3D metrical–topological model of a university campus or other extended urban region from labeled 2D floor plan geometry. An exhaustive classification of adjacency types is provided for a typical infrastructure, including roads, walkways, green-space, and detailed indoor spaces. We extend traditional lineal techniques to 2D open spaces, incorporating changes in elevation. We demonstrate our technique on a dataset of approximately 160 buildings, 800 floors, and 44,000 spaces spanning indoor and outdoor areas. Finally, we describe MITquest, a web application that generates efficient walking routes.

The Graphical Properties of MANETs in Urban Environments
A large portion of MANET research has focused on free-space environments. In this extended abstract, MANETs in urban environments are investigated. Specifically, the graphical properties of the ad hoc topology are investigated. This includes examination of the degree distribution and centrality. The spatial variation of these properties are also investigated. It is found that the graphs for urb...
