中断率是分析无线多传感后向散射通信系统的重要指标.针对后向散射多传感系统中的中断问题,基于经典的后向散射多传感通信模型,给出了对数正态阴影信道下中断率的闭式解.应用蒙特卡罗(Monte Carlo)仿真和数值积分的方法,分析了影响后向散射多传感通信系统中断率的相关因子.结果表明,蒙特卡罗仿真与数值积分具有很好的一致性,中断率的数值分析误差小于1.481%.同时,随着信号干扰加噪声比SINR门限值的增加,中断率也增加;如果SINR门限值过大,传感器间相互干扰影响很大;反之,如果SINR门限值过小,传感器间相互干扰影响很小,为后向散射多传感系统的可靠性分析和设计提供了参考.

Outage probability is a vital index in analyzing wireless multi-sensor backscatter communication. A classical model of multi-sensor backscatter communication system is used for analyzing outage probability. A closed-form solution of outage probability for a lognormal shadow channel is given. Using Monte Carlo simulation and numerical integration, factors affecting outage probability are analyzed. The result of Monte Carlo simulation is consistent with that of numerical integration. The outage probability error of numerical analysis is less than 1.481%. Meanwhile, with increase of the SINR threshold, the outage probability increases. If the SINR threshold is too large, mutual interference among sensors becomes severe. On the contrary, if SINR threshold is too small, mutual interference is greatly reduced. These conclusions provide a reference for analyzing reliability and designing of backscatter communication systems.
