Cooperative Event-Triggered Forwarding with Compressed Sensing in Multi-Hop Wireless Sensor Networks

To address the degradation of state estimation accuracy induced by channel fading in multi-hop wireless sensor networks, this paper proposes a novel approach that integrates cooperative communication, compressed sensing and an event-triggered forwarding strategy. By introducing cooperative relay nodes at the forwarding layer, the proposed method leverages spatial diversity gain to enhance the packet arrival rate \(γₖⁱ\). Simultaneously, compressed sensing is utilized to reduce the payload volume, which, combined with the event-triggered forwarding strategy to mitigate unnecessary transmissions, achieves a dual optimization of energy efficiency and reliability. Simulation results demonstrate that under low signal-to-noise ratio channel conditions, the proposed strategy significantly improves system stability while maintaining low energy consumption.
