TRUST -BASED APPROACH IN WIRELESS SENSOR NETWORKS USING AN AGENT TO EACH CLUSTER

Detection of malicious node in the neighborhood with minimal infrastructure and computations is a requirement. The existing models require more computation, storage, and complex security calculations. These models are inefficient in wireless sensor networks due to their resource limitations. Therefore, an agent-based approach that maintains the node’s current status is proposed in this research. In agent-based approach detection is possible through maintaining the ratings of each node. The ratings of a node will be done through the ratio of packet forwarded by packets received. Further, the ratings can be done using the E-commerce models. In E-commerce models, each node votes the successive node depending upon the ratio of packet forwarded by packets received. The update ratings will be done through Sporas formula or Molina’s formula or with a combination of both models. Further, the proposed agent-based framework uses reputation of a node through neighbouring nodes as part of trust calculation. The simulations were presented to calculate the trust of a node.
