Secure Acknowledgement based Misbehavior Detection in WSN (S-ACK)

Abstract

Security is a most significant challenge for generating a vigorous and consistent sensor networks, such as routing attacks have the capability to separate or isolate a sensor network from its Base Station (BS). Routing misbehavior in the network is that some malicious nodes will play in the route discovery and maintenance process but refuses to forward the data packets. In this paper, we propose Secure Acknowledgement (S-ACK) based Routing Misbehavior Detection in Wireless Sensor Networks (WSN). Objective: The objective of this scheme is to identify the node misbehavior and reduce the overhead in WSN. Methods/Statistical Analysis: This scheme consists of 3 phase such as Acknowledgement (ACK) phase, Secure Acknowledgement (S-ACK) phase and (Misbehavior Verification) MV phase. If the source does not get the acknowledgement from the destination during ACK phase, the source sent the S-ACK packet to the S-ACK phase. S-ACK phase generates the misbehavior report. The Misbehavior Verification phase verifies the misbehavior report is authenticated or not. Finding: The proposed misbehavior detection scheme is capable to attain high detection accuracy for routing attacks. Application/Improvements: The simulation result implies that the SACK provides better Packet Delivery Rate and reduces end-to-end delay.
