The lifetime of Energy-harvesting Wireless Sensor Networks (EH-WSNs) is ideally infinite. However, these networks are costly to implement, and unreliable due to unstable ambient energy. Consequently, Hybrid Wireless Sensor Networks (HWSNs) consisting of Energy-harvesting Sensor Nodes (EHSNs) and Battery-powered Sensor Nodes (BPSNs) gain the spotlight. Nevertheless, HWSNs confront the volatility of BPSNs that result in the unreliability of the whole network. In order to solve this issue, we design a reliable Hybrid MAC (H-MAC) protocol targeting HWSNs. The proposed protocol consists of two important mechanisms, i.e. Hybrid Polling and Hybrid Duty-cycle Scheduling. The former emphasizes on setting different polling transmission probabilities for BPSNs and EHSNs, while the latter on configuring different duty cycles. Both mechanisms are designed to suppress the energy dissipation of BPSNs by effectively utilizing the renewable energy of EHSNs, so that the stability of network can be guaranteed within its lifetime. Simulation results demonstrate that the average lifetime of BPSNs is significantly increased compared to the baseline protocols. Furthermore, the network transmission performance is also promoted. |
