Trust-Based Defence Model Against MAC Unfairness Attacks for IoT

Research Output

The vulnerability of IoT networks makes channel access security a serious problem. The IEEE 802.15.4 MAC (Media Access Control) layer faces the risk of attacks from malicious nodes which attempts to get a dominating position and hold unfair advantages over the other nodes. In this paper, we address MAC unfairness attacks where attackers attempt to bypass the MAC priority. We propose a MAC-trust-based model to handle unfairness attacks while maintaining channel access to all participating nodes. In our scheme, a Pan Coordinator Manager (PCM) cooperates with PANs and Coordinators to detect malicious behavior, calculate trust values for participating nodes, and maintain a blacklist of malicious nodes. Our model modifies Guaranteed Time Slots (GTS) allocation policies according to nodes’ trust values.
