This paper presents our proposed routing mechanism for wireless mesh sensor network which support autonomic Internet of Things (IoT). Autonomic IoT is the creation of self-management capability in the IoT system by embedding some autonomic properties, with the goal of freeing human from all details of the operation and management of the system while providing the system to always operate properly. The proposed routing provides a mechanism to embed some autonomic properties in the IoT edge network, i.e. self-configuration, self-healing, selforganization, and self-energy-awareness. It supports the IoT system to face the challenge of resource constraint of IoT nodes, as it becomes one of the top challenges in IoT edge network. A hierarchical routing fashion with residual energy consideration is used to form a lightweight routing algorithm. We provide a validation through computer simulations to investigate the routing performance for large number of IoT sensor nodes. We take an energy-aware straight path routing as the comparison. As the result, our proposed routing successfully produces longer network lifetime and lower total energy consumed.
