Securing Wireless Networks Using Trust Based Adaptive Acknowledgement

摘要

Wireless Sensor Networks (WSN) are prone to various attacks. Different schemes have been used to reduce the malicious nodes from the network. In the environment of WSN, various schemes have used ACKs to detect routing misbehavior or malicious nodes. ACK based routing solves ambiguous collisions, receiver collisions, and will use limited transmission power. To improve security in wireless networks the best mechanism Trust. In this paper we present a Trust Based Intrusion Detection System (IDS) for Wireless Sensor Networks (WSN) based on Kalman filter to predict Trust of a given node. The proposed method resulted in improved packet delivery ratio and decreased end to end delay when compared it with MS-MAC technique which makes use of flooding based routing. We show that the proposed method is efficient.
