ABSTRACT
With a growing need to better understand our environments, the Internet of Things (IoT) is gaining importance among information and communication technologies. IoT will enable billions of intelligent devices and networks, such as wireless sensor networks (WSNs), to be connected and integrated with computer networks. IoT has become a new focus for both industry and academia involving information and communication technologies (ICTs), and it is predicted that there will be almost 50 billion devices connected with each other through IoT by 2020. Routing Protocol for Low Power and Lossy Networks (RPL) is a distance vector routing protocol. It does not have predefined topology but will be generated through the construction of Destination-Oriented Directed Acyclic Graphs (DODAGs). It is obvious that any routing mechanism involves significant control overhead in a large-scale network. Particularly in a multi-hop network, an effective message control mechanism is significantly important in reducing network overhead and balancing limited network resources.
