Abstract

The invention discloses a Mesh and clustering combination-based wireless sensing network channel scheduling method. Each node point carries out respective task dispatching periodically in the network, and the communication among the node points is realized. The channel scheduling method adopts the main concept that in intra-cluster communication, after a dispatching cycle of a upper layer node point is formed, a lower layer node point can be informed in a periodic broadcast Beacon frame form, so that the lower layer node point is added into the clusters established by the upper layer node point and to maintain the clock synchronization of the upper node point; in inter-cluster communication, backbone nodes takes charge of route setup and inter-cluster data transmission. The channel scheduling method effectively solves the problems that the interference of the intra-cluster high power communication to the inter-cluster communication and the excessive idle listening of the node point through the division of the intra-cluster communication time interval and the introduction of the sleeping mechanism of the node point. The channel scheduling method provided by the invention is suitable for a certain part of typical wireless sensing network utilization, and simultaneously can be used as an expanding basis for other wireless sensing network.
