Parasitism time synchronization of centralized communication guardian

摘要

The plural nodes and, one or being the plural hubs, each hub, one which possesses the communication link with the aforementioned plural nodes or offers the parasitic time synchronization network which includes with the plural hubs and one or the group of guardians. Each node, transmits the data, in order to receive, conforms, the aforementioned one or through the plural hubs, in order to communicate with the other all node, conforms. In each case the aforementioned communication link with one hub and the aforementioned plural nodes, defines the communication channel. Each guardian is related to one communication channel. Each node, among those the aforementioned one or through the hub which among of the plural hubs is related, can allot the time slot which transmitting the data is permitted. The guardian of the channel which it is related the description above blocks the propagation of data transmission between the aforementioned plural nodes which mind the hub which it is related permits among the aforementioned plural nodes data transmission from just one, the aforementioned guardian receives the cluster of the beacon which is formed by the plural among the aforementioned plural nodes periodically.
