Wireless sensor networks are becoming increasing important due to their outstanding ability to detect and transmit real-time and wide application in many fields. Reducing energy consumption and extending lifetime of networks are important targets in the design of wireless sensor networks. In this paper, an optimal scheme is proposed based on mixed routing. The switch factor is presented and the optimal problem is converted into a nonlinear programming problem. The target is to optimize the lifetime of bottleneck node. The optimal solution is gained by the sub-gradient iterative algorithm. The simulations show that the lifetime of the networks is extended effectively.
