Research on Modeling of Sensor Nodes Reliability

Abstract:

To establish the model of wireless sensor network reliability, the sensor nodes’ reliability was assumed to be exponential distribution. By the methods of MLE and K-S , reliability distribution function of sensor nodes was verified in line with two parameters Weibull distribution . Basing on experimental dates , reliability distribution function of sensor nodes accorded with two parameters Weibull distribution and exponential distribution were in Eq.9 and Eq.10. Comparative results in Fig.5 shows that the two parameters Weibull distribution exceeds the exponential distribution to describe the distribution of sensor nodes.
