| Abstract: | Wireless data broadcasting allows that the realization of large-scale application systems serving mass mobile users is possible. Existing data broadcasting system does not support the mobile real-time transactions. Considering the inherent limitations of wireless broadcast environments,mobile of data users, especially mobile from one unit to another, and the deadlines of mobile real-time transactions, in this paper, a better transaction model segmented transaction model combined static and dynamic segmentation was given for real-time data broadcasting. |
