Abstract: Wireless sensor and actor network (WSAN) refer to wireless sensor network (WSN) added by actors. Sensors detecting a physical phenomenon, while the role of actors is to collect and process sensor data perform appropriate actions. The coordination of sensors and actors is important research aspect in WSAN. Thus the paper presents a dynamic clustering algorithm, which cluster formation depended on the event. This way, only the event area is clustered and each cluster consists of a actor and those sensor nodes that send their data to the actor. This dynamic clustering algorithm is able to make a decision that which sensors communicate with which actors.

Key words: WSN, WSAN, Coordination, Cluster

摘要： 带执行器节点的无线传感器网络（WSAN）是指在无线传感器网络中加入执行器，传感器用于检测物理环境信息，执行器收集和处理这些检测数据，并作出适当的执行任务。传感器和执行器的协作是WSAN研究的一个重要内容，本文就此提出了一个动态分簇算法，根据事件发生的实际情况，仅仅对该事件区域分簇，每个簇包括一个执行器节点以及传送数据到该执行器节点的传感器节点。通过这种分簇，可以决定传感器与哪个执行器通信以及路由方式。
