Abstract

Abstract:

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.

Key words: backscatter, signal to interference ratio, outage probability, closed-form solution
