Abstract: A Wireless Sensor Networks  Is A Network Used For Computing, Sensing. There Are Various Resource Constrains In Wsn Like Energy, Computational Power, Memory, Design Challenges. The Problem In The Sensor Nodes That Nodes May Get Compromised. The Trust Management Schemes Consist Of Effective Tools To Identify Unexpected Behavior Of Sensor Nodes In The Network. Trust Has Been Effective And Provides Secure Mechanism For Managing Each Sensor Node In Network. In This Paper We Investigated Some Trust Techniques And Present The Effective Methodologies To Calculate The Trust Of A Sensor Node To Eliminate The Selfish Or Compromised Nodes In The Network.
Keywords: Entropy, Reputation, Bayesian, Fuzzy model, Trust.
