Abstract
The internet of things (IoT) has rapidly grown in the past decade. Due to the heterogeneity and energy limitations of IoT devices, adopting efficient management practices for developing IoT applications is a challenging task. Software defined networking (SDN) is a novel approach that decouples the control plane from the data plane, enabling network administrators to manage their networks more efficiently. This paper proposes an energy-aware routing mechanism by leveraging the capabilities of SDN. Firstly, the SDN controller establishes several optimal clusters using fuzzy logic and the improved African vulture optimisation algorithm (IAVOA). Then, the controller computes optimal routes by combining the fuzzy logic system. Applying this mechanism enables data packets to be routed through IoT devices with sufficient energy, leading to prolonged network lifetime and improved quality of service (QoS). Simulation results confirm that the proposed solution significantly improves energy efficiency and QoS in terms of packet delivery ratio.
