Efficient embeddings of grids into grids

open access: yesDiscrete Applied Mathematics, 2001
An embedding of a graph \(G\) into a graph \(H\) is a pair of two mappings: an injection \(\phi:V_G\mapsto V_H\) and a routing scheme that maps \(E_G\) into the set of paths in \(H\). The authors consider two embedding parameters: dilation, defined as the length of a longest path in the image of the routing scheme, and the edge-congestion, defined as ...

Grid Object Description: Characterizing Grids [PDF]

open access: yesIFIP/IEEE Eighth International Symposium on Integrated Network Management, 2003., 2003
We present a new data model approach to describe the various objects that either represent Grid infrastructure or make use of it. The data model is based on our experiences and experiments conducted in heterogeneous grid environments. While very sophisticated data models exist to describe and characterize, e.g.

From the grid to the smart grid, topologically [PDF]

open access: yesPhysica A: Statistical Mechanics and its Applications, 2016
The Smart Grid is not just about the digitalization of the Power Grid. In its more visionary acceptation, it is a model of energy management in which the users are engaged in producing energy as well as consuming it, while having information systems fully aware of the energy demand-response of the network and of dynamically varying prices.
