Abstract

IoT networks are growing rapidly with the addition of new sensors, nodes and devices to existing IoT networks. Due to the ever-increasing demand for IoT nodes to adapt to changing environment conditions and application requirements, the need for reconfiguring these already existing IoT nodes is increasing rapidly. A reconfiguration of an IoT network includes alterations to the devices connected, changing the behavioural patterns of the devices and modifying the software modules that control the IoT network and devices. Reconfiguring an already existing IoT network is a challenge due to the amount of data loss and network downtime faced when carrying out a reconfiguration procedure in a limited power supply environment. This paper proposes an architecture for trusted dynamic reconfiguration of IoT nodes with the least amount of data loss and downtime. The proposed approach uses multiple IoT nodes to facilitate dynamic reconfiguration.
