The process of data forwarding in sensor networks is analogy to electric charge moving in electrostatic field. By this analogy, a method which abstracting a sensor networks to a Gravitational Field is proposed in this paper. In this gravitational field, sink node has gravitational to the data and data can flow to sink under this gravitational. Based on this gravitational field, a routing method which applies well in Multi-Sink sensor networks is proposed in this paper. This method has a lower time and space complexity, and it can adapt to the variety of the networks size dynamically. Theoretic analysis and simulation results indicate that: the routing method this paper proposed can decrease the energy consuming of data transmission effectively, reduce the data packet discard rate, uniform the networks' loads, and prolong the lifecycle of the networks.
