AbstractA trust model of sensor nodes in WSNs that named AEMP is proposed. AEMP means ‘Addition Encouragement, Multiplication Punishment’. Compared with current other models, AEMP works with simple calculation and needs fewer resources. The paper also discusses different values’ influence of parameters to evaluation performance. Then the model integrated direct and indirect trust value is discussed. This integration model can identify a bad node more quickly, but it may also conduct the problem of malicious evaluation. For each kind of model, a lot of simulation experiments are done to test its performance. AEMP models can enhance WSN ability to against attacks from insidenetwork. And they also afford new routing algorithm while designing a WSNs routing protocol.
