In order to solve these issues, we first propose a framework for trust evaluation to identify the malicious behavior of sensor nodes and then give a localized distributed protocol, called energy and trust aware mobile agent migration (ETMAM) protocol for periodic data gathering application.
3. Trust Evaluation: For complex, distributed environments (e.g., Cloud computing) we introduce a categorization of mechanisms that are relevant for trust evaluation that – to the best of our knowledge – have not been discussed in this context before: .
The indirect trust evaluation mechanism of the vehicle node is established based on the recommended trust from other nodes in VANETs.
Reliability evaluation of trust The reciprocal of trust evaluation deviation from other users to the target user is expressed as Rel ( t ) = 1 Var ( Tr ij ) (9).
As compared to the existing trust models in literature, the proposed model not only increases the accuracy of trust evaluation but also enhances the performance of the model in different traffic densities.
This study first introduces a previously proposed trust evaluation model for evaluating trust over the lifecycle of VPTs.
In the indirect trust evaluation, we make use of the correlation coefficient of the recommendation trust value to distinguish the malicious nodes.
This paper presents results of a controlled experiment conducted to collect human behavior data through a series of trust evaluation tasks.
To solve the problem and improve the accuracy of trust evaluation, this paper proposes a security authentication method based on trust evaluation.
The historical trust values, stored in the list, are the last value of trust evaluation by the last accessed network, and this value can be used as reference values of trust in the next access to the networks.
