Wireless sensor networks have a wide range of applications in military and civilian domains.Wireless sensor networks are prone to attacks as they are usually deployed in a hostile environment. Packet dropping and modification are the common attacks that can be launched by an adversary to disrupt communication. In this paper, a scheme is proposed to efficiently detect packet droppers and modifiers. The sensor nodes are secured using distributed key generation mechanism. Depending upon the packet dropping, nodes are categorized as bad nodes and suspiciously bad nodes. Simulation of the proposed scheme is done using NS2 and effectiveness of the scheme is verified.

Abstract


Wireless sensor networks have a wide range of applications in military and civilian domains.Wireless sensor networks are prone to attacks as they are usually deployed in a hostile environment. Packet dropping and modification are the common attacks that can be launched by an adversary to disrupt communication. In this paper, a scheme is proposed to efficiently detect packet droppers and modifiers. The sensor nodes are secured using distributed key generation mechanism. Depending upon the packet dropping, nodes are categorized as bad nodes and suspiciously bad nodes. Simulation of the proposed scheme is done using NS2 and effectiveness of the scheme is verified.
