Hierarchical decompositions of graphs are interesting for algorithmic purposes. There are several types of hierarchical decompositions. Tree decompositions are the best known ones....
We study the utility of dynamic frequency agility in realworld wireless sensor networks. Many view such agility as essential to obtaining adequate reliability in industrial enviro...
A detailed understanding of the many facets of the Internet’s topological structure is critical for evaluating the performance of networking protocols, for assessing the effecti...
