Three tabu search methods for the MI-FAP applied to 802.11 networks

Sacha VaroneNicolas Zufferey — 2008

RAIRO - Operations Research - Recherche Opérationnelle

Wireless LAN using IEEE 802.11 networks are now widely deployed at home by residential users or in hot spots by telecommunication operators. A hot spot is a place where a set of access points (APs) are located nearby each other and can serve many users. Since perturbations can degrade the quality of the signal, a careful channel assignment to each AP has to be done. Channel assignment of APs at hot spots, and more generally setup configuration and management, is still often done manually. In this...

A note on tree realizations of matrices

Alain HertzSacha Varone — 2007

RAIRO - Operations Research

It is well known that each tree metric has a unique realization as a tree, and that this realization minimizes the total length of the edges among all other realizations of . We extend this result to the class of symmetric matrices with zero diagonal, positive entries, and such that for all distinct .
