For the node disturbed in the wireless sensor networks

based on physical transmission characteristics of wireless link

which can not only guarantee successful data transmission and receiving

but also ensure node transmission power and connectivity

an energy efficient routing algorithm of interference adaptive for wireless sensor networks is proposed.This algorithm finds the minimum energy link through improving the interfering node energy or switch to channel outside interference zone

which ensures total energy of the entire network path minimum or approximate minimum.Introduce an energy confidence level α to prevent interference nodes constantly improve energy or to die out so fast.Simulation experiments show that the algorithm can balance the energy consumption of the whole network and prolong survival time of wireless sensor networks.
