An energy-efficient routing method is proposed for a static wireless sensors network, which consists of a large number of energy-constrained sensors and a few hubs as the cluster heads of sensors. By adopting a clustered traffic topology, with additionally deployed router sensors, an energy- efficient routing design can be achieved to prolong the sensor lifetime with the trade-off increased energy consumption at the entire network level. Simulations also suggest that using dense deployment of routers is capable of achieving the energy-minimal routing design, where the overall energy consumption can be even lower than without the routers.
