摘　　要：为解决物联网的多重依赖问题,在传统的GPGP机制中引入了图论思想,通过建立有向图,标识每个完整的依赖关系,进而解决物联网零结构条件下的任务协调问题,并对传统GPGP机制的"探测协调关系"过程进行了改进,以传递改进GPGP机制所需的额外信息。与传统GPGP相比,尽管改进GPGP机制需要传递更多的间接协调关系信息,但不会明显增加通讯代价。In order to solve multiple dependency problem of Internet of things, the idea of the graph theory is introduced to the traditional GPGP mechanism. Through establishing of a directed graph and the identificating each complete dependen- cy, the coordination problem of the task on the Internet of thins which is zero infrastructure is solved. The processing of ＂de- tect coordination relationships＂ of GPGP mechanism is improved,which is used to transmit the necessary additional informa- tion. Compared with the traditional GPGP mechanism, although the improved GPGP mechanism needs to transmit much more indirect coordination information among agents, it does not cost too much communication bandwidth.
