With the rapid proliferation of Internet of Things (IoT) devices across diverse applications ranging from healthcare and agriculture to smart cities and industrial automation energy efficiency has emerged as a critical design constraint. This paper proposes hybrid modulation strategies as a viable approach to significantly reduce the power consumption of IoT transceivers while maintaining acceptable performance in terms of data rate and reliability. A comprehensive analysis is carried out by combining amplitude shift keying (ASK), frequency shift keying (FSK), and phase shift keying (PSK) modulation schemes based on the instantaneous channel condition and required data throughput. Simulation results validate that the proposed hybrid scheme achieves superior energy efficiency and reduced bit error rate (BER) compared to traditional single-modulation techniques. This research paves the way for intelligent, context-aware modulation in next-generation ultra-low-power IoT devices.
