Abstract

The process of data forwarding in sensor networks was analogy to electric charge moving in electrostatic field. By this analogy, a method which abstracted a sensor networks to a Gravitation Field was proposed. In this gravitation field, sinks had gravitation to the data and data could flow to sinks under this gravitation. Based on the gravitation field produced by sinks, a routing algorithm worked well in Multi-Sink sensor networks was proposed. This algorithm had a lower time and space complexity, and it could adapt to the variety of the network size dynamically. Theory analysis and experiments had proved that the method used less energy in communications, had a lower packet discard rate, and it could prolong the lifecycle of the networks effectively.
