An optical multistage interconnection network for optimal all-to-all personalized exchange, They propose an optical multistage interconnection network to realize an all-to-all personalized exchange that only requires one pass to send a message from each node to a different node (to realize a permutation). Hence, the new optical multistage interconnection network only requires n-1 passes for an ...

Let E be a coanalytic equivalence relation on a Polish space X and (An)n∈ù a sequence of analytic subsets of X . We prove that if lim supn∈K An meets uncountably many E-equivalence classes for every K ∈ [ù] , then there exists a K ∈ [ù] such that T n∈K An contains a perfect set of pairwise E-inequivalent elements. §

Cellular data and communication networks are usually modeled as graphs with each node representing a base station in a cell in the network, and edges representing geographical adjacency of cells. The problem of channel assignment in such networks can be seen as a graph multicoloring problem. We survey the models, algorithms, and lower bounds for this problem. — 1.1 INTRODUCTION In a cellular ne...
