Robust Cross-Layer Security Framework For Internet of Things Enabled Wireless Sensor Networks

The significant development of Internet of Things (IoT) paradigm for monitoring the real-time applications using the wireless communication technologies leads to various challenges. The secure data transmission and privacy is one of the key challenges of IoT enabled Wireless Sensor Networks (WSNs) communications. Due to heterogeneity of attackers like Man-in-Middle Attack (MIMA), the present single layered security solutions are not sufficient. In this paper, the robust cross-layer trust computation algorithm for MIMA attacker detection proposed for IoT enabled WSNs called IoT enabled Cross-Layer Man-in-Middle Attack Detection System (IC-MADS). In IC-MADS, first robust clustering method proposed to form the clusters and cluster head (CH) preference. After clustering, for every sensor node, its trust value computed using the parameters of three layers such as MAC, Physical, and Network layers to protect the network communications in presence of security threats. The simulation results prove that IC-MADS achieves better protection against MIMA attacks with minimum overhead and energy consumption.
