Abstract:Efficient broadcast in wireless sensor networks can exploit backbone structures, in relation to connected dominating sets in graphs. This paper proposes the construction of a backbone for broadcast in heterogeneous wireless sensor networks having minimum energy consumption and a delay bounded by a predefined constant hmax. For the purpose of the paper, we assume the sensors composing the network have an energy belonging to [Wmin; Wmax] such that Wmax = c * Wmin where c is a predefined constant. To address this… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
