Countering Node Misbehavior Attacks Using Trust Based Secure Routing Protocol
Abstract: Wireless sensor
networks have gained remarkable appreciation over the last few years. Despite significant
advantages and tremendous applications, WSN is vulnerable to variety of
attacks. Due to resource constraint nature of WSN, applicability of traditional
security solutions is debatable. Although cryptography, authentication and
confidentiality measures help in preventing specific types of attacks but they
cannot safeguard against node misbehavior attacks and come at significant cost.
To address this problem, we propose a Trust Based Secure Routing Protocol
(TBSRP) which relies on distributed trust model for the detection and isolation
of misbehaving nodes. The TBSRP aims to establish shortest path that contain all
trusted nodes, identify packet forwarding misbehavior caused by malicious and
faulty nodes and reroute the traffic to other reliable paths. The performance
of TBSRP is evaluated in terms of packetdelivery ratio, average end-to-end
delay and normalized routing load. Simulations results show thatTBSRP can
achieve both high delivery ratio and throughput in presence of various numbers
of misbehaving and faulty nodes.
