Neighbor discovery (ND) protocols are used for establishing a first contact between multiple wireless devices. The energy consumption and latency of this procedure determined by the parametrization protocol. In most existing protocols, reception transmission temporally coupled. Such schemes referred to as <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999...

Nearest Neighbor (NN) searching is a challenging problem in data management and has been widely studied in data mining, pattern recognition and computational geometry. The goal of NN searching is efficiently reporting the nearest data to a given object as a query. In most of the studies both the data and query are assumed to be precise, however, due to the real applications of NN searching, suc...
