CMNTS: Catching malicious nodes with trust support in wireless sensor networks

Abstract

Abstract-Security in wireless sensor networks is critical due to its way of open communication. In this paper we have considered suite of attacks -packet modification, packet dropping, sybil attack, packet misrouting, and bad mouthing attack, and provided a solution to detect attacks. 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 and trust on parent as a routing path marker and encrypts only the bytes added by node in packet before forwarding to parent. Sink can identify the malicious node based on trust value and node identities marked in packet. Child node observes the parent 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 chooses the parent node at the beginning of a round based on its own observation on parent. Simulated the algorithm in NS-3 and performance analysis is discussed by comparing the results with other two recently proposed approaches. With the combination of trust factor 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.

A Survey on Security in Wireless Sensor Networks

“…In [11], the trust support schema is found to identify malicious nodes with high detection rates and low incidence of false detection. However, it focuses on specific attacks related to the packet only; many other types of attacks have not been considered for this solution.…”

“…In [11], a solution is proposed for catching malicious nodes with trust support in WSNs (CMNTS); this targets specific WSN attacks by malicious node, including packet modification, packet dropping, Sybil Attack, packet misrouting and bad-mouthing attack. CMNTS initiates the process by creating a parent-child tree contains related information in a sink node.…”

CoopECC: A Collaborative Cryptographic Mechanism for the Internet of Things

“…Confidentiality ensures that information should never flow in a clear way between nodes, especially in critical applications such as military and healthcare. The data will be encrypted and, therefore, not interpretable and understandable by eavesdroppers [8]. Then, authentication protects the network against identity theft attacks by verifying the identity claimed by a node.…”

Semi Markov process inspired selfish aware co-operative scheme for wireless sensor networks (SMPISCS)

“…In addition, Trust Support-based Malicious Node Determination Scheme (TS-MNDS) was proposed mainly for detecting and also for preventing malicious selfish nodes in the sensor network (Prathap et al 2016). In this TS-MNDS, the data dissemination between each sensor node and the sink is always facilitated with selection of parent node.…”
