An Energy-Efficient Routing Scheduling Based on Fuzzy Ranking Scheme for Internet of Things

Internet of Things (IoT) is a wireless network of various battery-powered sensing units. Due to the limited battery capacity, the non-accessible/abandoned nodes demand more energy to be reached or re-integrated to keep the network connected. When a specific tree topology for routing, called Destination Oriented Directed Acyclic Graphs (DODAG) is used, isolated nodes spend maximum energy on the assigned task during data transformation from the sensor field to the DODAG root. The nodes closer to the DODAG root need to rely on faraway nodes and resource-burden constrained nodes to lead to the quick energy drain. It brings an idea of IoT network nodes in which an extra amount of energy provide to the longer-time alive nodes. This paper proposes an ARFOR-Adaptive ranking fuzzy-based energy-efficient opportunistic routing protocol for sustainable IoT applications. The proposed protocol consists of Parent Node (PN) that acts as a head node in a cluster to aggregate the packets to DODAG root; and Volunteer Node (VN) acts as a forwarder to transfer the packets to PN with threshold energy limits to increase network lifetime during transmission cycle. The proposed VN selection is based on fuzzy parameters such as Canberra distance, residual energy, and threshold. The simulation outcomes depict that the ARFOR fairly justifies the network timeline requirement with maximum percentage area coverage. The percentage gain in terms of network lifetime is comparatively significant for a lower number of VN.
