Abstract: To balance the energy consumption of nodes in Wireless Sensor Network (WSN), the authors proposed a routing protocol to transmit the network health state information based on clustering routing algorithm, named Event-Driven State Monitoring Information Routing (ED-SMIR). ED-SMIR adopted the way with single-hop turning to multi-hop in rotation according to energy consumption rate. For the route from cluster head to the sink, ED-SMIR took multi-hop routing. The simulation results show that, compared with LEACH and EDBCM, ED-SMIR has less energy consumption, and it can balance the energy of the entire network and extend the survival time of network effectively.
