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.
