Research of the QoS Routing Algorithm for WSN Based on Vague Sets

In this paper,on the basis of the measurement parameters,such as energy,delay,reliability,and other factors,which are represented as vague sets,multi-criteria evaluation of fuzzy decision routing algorithm based on vague sets is proposed.By comparing the degree of membership,non-membership,Vague sets distance and similarity values,it selects the optimal network path.Numerical experiments show that the proposed algorithm can solve the multi-criteria optimal QoS routing selecting problems,which are in the uncertainty link of complex environment among wireless sensor networks.
