AN ORTHOGONAL SPECTRUM SHARING SCHEME FOR WIRELESS SENSOR NETWORKS

An orthogonal spectrum sharing scheme for wireless sensor networks

Abstract It is not economically viable to allocate a dedicated spectrum band to wireless sensor networks (WSNs).Moreover, sharing a spectrum band with incumbent (primary) system compromises the reliability and performance of both the systems due to interference from one system to another.In this article, we address this bostik roll-cote limitation

A Nonlinear Radio-Photon Conversion Device

The article analyzes existing materials and click here structures with quadratic-nonlinear optical properties that can be used to generate a difference frequency in the terahertz and sub-terahertz frequency ranges.The principle of constructing a nonlinear optical-radio converter, based on an optical focon (a focusing cone), is proposed.Based on the
