SDN-Based Energy-Efficient Routing Architecture for Wireless Sensor Networks

Abstract

Wireless Sensor Networks (WSNs) are made up of sensor nodes that have limited resources. These sensor nodes keep collecting data and sending it to a sink or gateway. Because of battery power, changing traffic patterns, high communication overhead, and poor routing choices, the network lifetime and reliability can drop significantly. Software-Defined Networking (SDN) offers a programmable way to manage networks. This can help make routing decisions and improve how network resources are used in WSNs. This paper introduces an SDN-Based Energy-Efficient Routing Architecture for Wireless Sensor Networks. In this architecture, an SDN controller keeps track of the network’s state. It checks the energy levels of each sensor node. Picks the best communication paths dynamically. The architecture separates control functions from data forwarding. This allows routing to change based on energy, link quality, and how far nodes are from each other. A simulation study is used to compare the proposed method with a WSN routing method. The comparison uses performance measures, including energy consumption, packet delivery ratio, throughput, end-to-end delay, routing overhead, and network lifetime. The proposed architecture is expected to cut down on wasted energy. It should also ensure reliable data delivery and help the sensor network last longer. The study shows that SDN-based centralized control can be very effective. It can lead to energy- adaptive wireless sensor network designs. These designs are well-suited for Internet of Things (IoT) systems and smart monitoring applications.
