Abstract:
Trust is an important factor in transferring data from the source to destination in wireless sensor networks. If any sensor node fails to transfer the data, the Dynamic Source Protocol calculates the alternate path. Currently, the Dynamic Source Protocol does not have any built-in functionality to calculate an alternate path if the path has a malicious node. Intruder detection system can detect the malicious node. However, intruder detection system is very expensive for wireless sensor networks and there is no guarantee in detecting a malicious node. In the current research, a trust-based approach is recommended to minimize the overheads of intruder detection system and detect the abnormal behavior nodes. The proposed model uses the repeated games to detect faulty (malicious) nodes through the cooperative effort in the sensor network and judges the trust of successive nodes. Further, the research includes the trust model with reliable neighbors and query-based trust calculation. Simulations were presented for normalized payoff of packet dropping, average discount payoff, and trust relation.
