摘要: System lifetime of wireless sensor networks (WSN) is inversely proportional to the energy consumed by critically energy-constrained nodes during RF transmission. In that regard, modulated backscattering (MB) a promising design choice, in which send their data just switching antenna impedance and reflecting incident signal coming from an source. Hence, passive (WPSN) designed operate using MB do not have constraints conventional WSN. However, communication performance WPSN directly related coverage provided over field are deployed. this letter, analytically investigated. The required number sources obtain interference-free connectivity with determined analyzed terms output power transmission frequency sources, network size, source node characteristics.
