Modified reactive route discovery algorithm for constrained machine to machine communication in low power and lossy networks

Abstract

RPL builds a DODAG to enable routing for a source-destination pair in a network in order to allow point-to-point data transmission in LLNs. The source node sends its message to the root node, and the root helps route messages between the source and the destination. The root node is responsible in routing and preserving the route. When using RPL in point-to-point communication, low power and lossy networks are subjected to extreme energy depletion due to the routing algorithms that operate within the nodes and the energy used when nodes communicate. Because network performance is highly dependent on the energy available in the network nodes, energy reservation mechanisms for longer periods of time should be introduced. Therefore, the purpose of this study is to develop a modified routing mechanism that reduces the waste of energy and to increase the packets delivered between the restricted low-power and lossy network nodes described in RPL (RFC 6550) for machine-to-machine communication in routing data packets. This thesis follows Design Science Research (DSR), which is seen as a research practice that develops new or invents, creates inventive objects to fix problems or enhance the accomplishment of those new innovative artifacts, rather than describing or attempting to make sense of the current reality from it. It produces and assesses IT objects that are meant to address certain organizational challenges identified. The suggested solution presented satisfactory results in the grid case, where the network was sparse and the number of adjacent nodes was stable, demonstrating its scalability and achieving a PDR of between 75 percent and 80 percent. In comparison, with the increase in the number of nodes, the P2P-RPL solution reduced its efficiency. The justification for this action was the dependence on a set root node to deliver the messages
