Such a technological solution provides an adequate level of pervasiveness mandatory for the observation of complex environmental phenomena in both civilian [2] and military applications as for example dangerous areas surveillance, target tracking, and intrusion detection [3]. %D 2011 %I University of Trento %A Federico Viani %A Massimo Donelli %A Giacomo Oliveri %A Andrea Massa
