— Directional antennas are a promising option for use in ad-hoc networks for a variety of reasons, such as increased spatial reuse, reduced interference and enabling more effici...
We consider the following problem for wireless ad hoc networks: assume n nodes, each capable of communicating with nodes within a radius of r, are distributed in a ddimensional re...
: Recently, researchers have discovered that many of social, natural and biological networks are characterized by scale-free powerlaw connectivity distribution and a few densely po...
—In this work we develop a distributed boundary detection algorithm, dubbed Coconut, for 3D wireless sensor networks. It first constructs a tetrahedral structure to delineate th...
We study the problem of computing a family of connected dominating sets in wireless sensor networks (WSN) in a distributed manner. A WSN is modelled as a unit disk graph G = (V, E)...
