设施环境中WSAN执行器节点协作算法研究

Actors Cooperation Algorithms in WSAN for Greenhouse Facilities

针对WSN技术应用于设施作物无法摆脱人力监控的局面,提出将WSAN技术应用于设施作物,并针对应用中存在的执行器节点之间的协作问题提出了一种执行器节点协作算法。首先利用执行器节点重新部署算法将执行器节点部署到执行器节点执行区域的中间,然后利用基于密封第一价的拍卖算法将事件区域发生的任务进行拍卖与求解。仿真试验结果表明所提协作算法可以实现设施作物应用中的控制任务被WSAN网络中的执行器节点以协作的方式有效并快速地分配和执行。

The WSN technology used in greenhouse facilities cannot get rid of the situation of human monitoring, so the WSAN technology was proposed to he applied in greenhouse facilities. A cooperative mechanism of actors in WSAN applied in greenhouse facilities was discussed, which consisted of a redeployment algorithm of actor （RDAA） and a real-time tasks assignment algorithm based on the sealed first price auction （RTAA- SFPA）. The RDAA algorithm was used to deploy the actors in the middle of the event region to achieve real-time response of the occurred events. RTAA- SFPA algorithm was used to take the occurred events as the tasks being assigned by method of sealed first price auction. The simulation results showed that the cooperative mechanism proposed had better performance on the assignment and solution of the tasks through actors cooperation for greenhouse facilities.
