Secured Routing System for Low Energy Networks

The Internet of things (IoT) is the network of different devices like sensors, actuators, and other different objects which have the capability to communicate without the need for human involvement. IoT mainly includes the devices which has low power and lossy networks (LLNs). These devices have limited resources like memory, energy, processing power, and bandwidth. These features leads the system in challenging environment which may end up in unstable state if proper security measures are not applied. IETF designed a protocol for routing mechanism of these devices known as routing protocol for low power and lossy networks (RPL). RPL is vulnerable to number of routing attacks and does not support mobility of nodes. This paper includes the study of different kind of threats possible on RPL. The proposed method for attack detection by using trust-based intrusion detection system considers trust value of participating nodes.
