LEACH (Low Energy Adaptive Clustering Hierarchy) [1] is one of the popular cluster-based structures, which has been widely proposed in wireless sensor networks. LEACH uses a TDMA ...
This paper discusses several distributed poweraware routing protocols in wireless ad-hoc networks (especially sensor networks). We seek to optimize the lifetime of the network. We...
Distance bounding protocols are used by nodes in wireless networks for the crucial purpose of estimating their distances to other nodes. Past efforts to analyze these protocols hav...
Many emerging applications in both wired and wireless networks need support of secure group communications. There have been many secure group communication schemes in the setting ...
The Steiner tree problem asks for a minimum cost tree spanning a given set of terminals S ⊆ V in a weighted graph G = (V, E, c), c : E → R+ . In this paper we consider a genera...
