DMN2SC: Detecting Malicious Nodes with 2-hop Secure Channel Support in Wireless Sensor Networks
Year: 2017
Type: article
Abstract: Security in wireless sensor networks is critical due to its way of open communication. In this paper we have considered suite of attacks and provided a solution to detect malicious nodes. In literature, many schemes have been proposed to mitigate such attacks but very few detect the malicious nodes effectively and also no single solution detects all attacks. In the proposed approach, each node chooses the parent node for forwarding the packet towards Sink. Each node adds its identity as a routing path marker and encrypts only the bytes added by a node in packet before forwarding to parent. Child node observes the parent, handles acknowledgement from 2-hop distance node and decides the trust on parent based on successful and unsuccessful transactions. Data transmission is divided into multiple rounds of equal time duration. Each node sends a trust value report via multiple paths to Sink at the end of each round. Sink identifies the malicious node based on the number of packets a node participates in forwarding and also based on the trust value report sent from each node for its parent. Each node chooses the parent node at the beginning of a round based on its own observation on parent to recover itself from malicious parent node. With the combination of trust factor, 2-hop acknowledgement and fixed path routing to detect malicious activity, simulation results show that proposed method detect malicious nodes efficiently and early, and also with low percentage of false detection, compared to other recently proposed approaches.
