Hierarchical and On-Demand Attack Defence Framework for IoT Devices

Abstract

Internet of Things (IoT) devices are lightweight such that they generally possess low battery power. Hence, the chances of battery exhaustion and flooding attacks are more. In order to perform attack response actions against various attacks, this paper proposes Hierarchical and On-Demand Attack Defence Framework (HOAD) for IoT security. In this framework, primary (PC) and secondary controller (SC) nodes are deployed in the network along with the IoT devices. The SC scan be moved on-demand by the PC. The response agent at PC will first establish a new route via the SCs by excluding the intruders and the suspected nodes. Then, it will resend the stored packets to their destination via the newly established route. The proposed HOAD framework is implemented in NS2 and compared with the MECshield framework. Simulation results show that the HOAD has reduced end-to-end delay, increased packet delivery ratio, and increased residual energy.
