Performance Evaluation of RPL Routes and DODAG Construction for IoTs

The rapid growth in the Internet of Things (IoTs) has change our life to be more intelligent and smart, the development in the Wireless Sensors Networks (WSNs), besides the wide use of the embedded devices in different area like industry, home automation, transport, agriculture and health care, which was led the Routing Over Low-power and Lossy-network (ROLL) working group to introduce the IPv6 Routing Protocol for Low-Power and Lossy Networks (RPL), therein the RPL nodes have organized topology as a Directed Acyclic Graph (DAG) and terminated at one root to form the Destination Oriented DAGs (DODAGs). In this paper by using InstantContiki3.0 and CoojaGUI we analyze the DODAG formations, the RPL control messages that are send downward and upward routes to construct and maintain
