“…Implementing IDS in IoT devices is difficult due to its typical features such as resource-constrained devices, specific protocol stacks and standards. Therefore, various protocols such as routing protocol for low power and lossy network (RPL) [Winter et al(2012) Winter, Thubert, Brandt, Hui, Kelsey, Levis, Pister, Struik, Vasseur, and Alexander], IPv6 over low power wireless personal area network (6LoWPAN) [Kushalnagar et al(2007) Kushalnagar, Montenegro, and Schumacher], IEEE 802.15.4 [Montenegro et al(2007)Montenegro, Kushalnagar, Hui, and Culler], message queuing telemetry transport (MQTT) [Quincozes et al(2019)Quincozes, Emilio, and Kazienko], constrained application protocol (CoAP) [Shelby et al(2014) Shelby, Hartke, Bormann, and Frank] can be utilized to enhance the security level. Due to intrinsic resource and computational constraints, traditional security methods cannot directly be applied to secure IoT systems.…”
