Distributed Scheduling Approaches in Wireless Sensor Network
无线传感器网络分布式调度方法研究

Wireless sensor network (WSN) is a resource constrained network system. Many kinds of scheduling approaches have been proposed to improve the performances of WSN. In this paper, the design principles and classification methods for distributed scheduling approaches of WSN are summarized. And the scheduling approaches are discussed and classified with respect to scheduling object. The fundamental mechanisms of some typical approaches are discussed further and the characteristics of each class are analyzed in detail. Comparison between the designed objects and the performance features of these scheduling approaches are presented. Finally, the current research situations for distributed scheduling approaches of WSN are summarized and the key aspects for further research are also suggested.
