Abstract
A node device for forming a multi-hop network is provided. The node device is configured to avoid interference from coexisting interfering networks and includes a transceiver configured to receive and transmit data with respect to a Destination Oriented Directed Acyclic Graph (DODAG) Information Object message (DIO message), a memory configured to store computer executable programs including an interfered-node count (IC), single-rate link count (SLC), multi-rate link count (MLC), hop count (HP), path communication latency (PCL) and an interference efficient and multi-rate supported routing program CoM-RPL, and a processor configured to perform steps of the computer executable programs. The steps include determining if the received DIO message indicates a new DODAG or an existing DODAG. In this case, if a determined result in the determining indicates the new DODAG and no single-rate link and no interfered node on a path of multi-hop network, the node device joins DODAG network and the processor selects a sender of the DIO message as a default parent, computes a rank for itself, updates DIO message with its rank, IC, SLC, TRM, HP, PCL and transmits scheduled DIO messages based on transmission rate mode.
