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

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 DODAG and the Rank computation by Objective Function (OF) for inconsistency and loop detection, also we evaluate the performance of the RPL based on the Expected Transmission Count (ETX) OF that enable RPL to select and optimize routes within RPL instance, as well as we evaluate the following metrics: The ETX Reliability Object (ETX), Radio Duty Cycle (RDC), energy consumption, the received packets by the motes and neighbor count. The simulation results show that the RPL control messages flow in consistent manner, the DODAG root able to connect to all of the neighbor motes, also Rank illustration shows no loops and DODAG topology consistent, as well as the ETX can essentially take control over DODAG formations and it has an effects in the RDC ratio, furthermore most of the motes show reasonable low power consumption, also the motes show acceptable number of the received packets.
