Abstract: Considering the flaw of LEACH and TEEN as well as the absolute impact on energy consumption of transmission distance，the network load balancing of the nodes，network with the greatest possible service life，this paper presents a multi-stage ring clustering routing algorithm（Multi-stage Cluster Based Ring Routing algorithm） MCBR.The algorithm takes into account how to reasonably partition the entire net into small cluster and elect head node，and taking into account impact of the transmission distance，a new routing mechanism is presented that effectively extends the lifetime of the network.The simulation result shows that the MCBR routing algorithm effectively decreases energy consumption.
