Forwarding Area-Tune Energy Efficient Geographic(FAEG) routing is proposed to solve the problem of data transmission in Wireless Sensor Networks(WSNs). In FAEG, the forwarding region of packet is controlled, and forwarding node set is constructed. The node with big weight is selected to transfer packet. By calculating the weight based on both the remaining energy of the node and the distance from the destination node, the remaining energy of the node is large and the node close to the destination node is qualified to firstly deliver the packet, which improves the routing stability. When a node encounters a routing void, the forwarding area is adjusted to select the node transmitting the packet in a wider area. Simulation results show that the proposed FAEG routing reduces energy consumption and improves packet transmission rate.
