Background and Objective: Two common attacks that can be launched by malicious nodes to disrupt the communication in multiple-hop sensor networks are Packet Droppers and packet modifiers. Numerous models have been proposed to moderate or endure such attacks, yet not very many can adequately and more efficiently distinguish the intruders. Materials and Methods: To address this issue, we propose a straightforward yet viable scheme, which can distinguish making trouble forwarders that drop or alter packet. Results: Extensive analysis and simulations have been led to check the adequacy and effectiveness of our scheme. © 2016, International Journal of Pharmacy and Technology. All rights reserved.
