The 6TiSCH architecture is widely used in Internet of Things applications due to its high reliability and low energy consumption. However, this structure, which is a combination of the RPL routing protocol and TSCH scheduling, is particularly vulnerable to sinkhole attacks. Sinkhole attacks manipulate the routing decisions of surrounding nodes by causing the malicious node to present itself as an attractive parent; a mobile attacker shifts this effect to different regions of the network by changing location, further increasing topological instability. The methods presented in the literature are largely focused on static attacker models, making them inadequate for detecting the anomalies caused by mobile sinkhole attacks. In this direction, Kagan-6T, a routing approach resilient to mobile sinkhole attacks in 6TiSCH networks, is proposed in this paper. Kagan-6T comprehensively analyzes the impact of attacks at the MAC and routing layers by combining movement/manipulation detection based on RSSI variance, TSCH channel-offset density analysis, and topological behavior assessment based on rank fluctuations. Experimental results conducted on Contiki-NG and Cooja have shown that Kagan-6T offers more stable performance than standard RPL and existing methods under a mobile sinkhole attack, both in terms of detection success and packet delivery rate.
