Based on directional diffusion algorithm,this paper proposes a novel cooperative wake-up routing algorithm(CWR algorithm) for wake-up mechanism in heterogeneous sensor networks.We substitute a high-cost node with the nearest low-cost node,which launches multi-hop diffusion.In particular,we add two steps:routing displacement and routing repair to establish network topology between low-cost nodes and their corresponding high-cost nodes,thus provide a necessary network topology foundation for wake-up mechanism.Simulation results demonstrate that our CWR algorithm is energy-efficient during wake-up process.
