Evaluation of Linear Topology Wireless Sensor Network’ s Reliability Using Improved Universal Generating Function Method
摘要
Abstract
This paper proposes an improved universal generating function( UGF) algorithm oriented sensing data fusion and uses it to evaluate the reliability of linear topology wireless sensor network.Firstly, a two-way continu-ous k out of n:F system model is established according to WSN topology and data transmission under PEGASIS protocol.Then, sensor node’ s universal generating function and composition operator are redefined according to the characteristic of data transmission and data fusion in WSN.Finally, the two-way continuous k out of n: F model is divided into two unidirectional models, and the reliability of two-way continuous k out of n:F model can be calculated by composing the reliability of two unidirectional models.An example is presented to test the pro-posed improved algorithm.The results show that the improved algorithm can effectively solve the problem of wire-less sensor network reliability evaluation.关键词
