Abstract

In wireless sensor networks (WSNs), due to the restricted resources of the nodes, are highly vulnerable to attacks at all network layers; however, the so-called “wormhole attack” is particularly challenging because it resists self-protective measures exclusively based on cryptographic protocols, this attack that not only diminishes the network capacity but also affects the reliability of information being transmitted. No emphasis was made towards the preventing the wormhole attack. In this paper a swarm-based framework that uses the security agents and security officer nodes. Preserving the legitimate packets coming from reserved route only, thereby discarding the contaminated packets has been proposed from another network.
