(The mutual conversion between the Ethernet data frame of the next generation cable digital TV transmission network and the data frame of the home wireless sensor network is studied. The important network element for mutual conversion is the convergence node. Point sink, reasonably plan the data frame structure on the Ethernet side, configure the frame structure share of the wired side and the wireless side, and the scheme conversion algorithm, which effectively realizes the wireless sensor network and Ethernet on the sink node. Data frame structure conversion for the network.)
