In a conventional wireless cellular system, signal processing is performed on a per-cell basis; out-of-cell interference is treated as background noise. This paper considers the be...
We propose a novel localized algorithm that constructs a bounded degree and planar spanner for wireless ad hoc networks modeled by unit disk graph (UDG). Every node only has to kn...
—To improve the performance of spectrum sensing, cooperation among Cognitive Radios (CRs) has been proposed recently as an effective solution. Most existing works require either ...
— Broadband access for all will be a key functionality in future mobile radio networks. Depending on the length and the characteristic of the radio wave propagation the performan...
Abstract-- Secure group key distribution and efficient rekeying is one of the most challenging security issues in sensor networks at present. In this paper, Latin square is firstly...
