Dynamic data broadcasting dispatching technology based on hyper graph in unsymmetrical network

Data broadcasting is an important technology to improve the retractility of mobile computation system in unsymmetrical network. In the paper, a kind of multi-disk broadcasting dispatching technology is presented based on hyper graph, which can determine the amount of disks, the contribution of data items to each disks and their relative frequency by computer. The theoretical analysis and experiment results indicate that the method can greatly improve the average visiting time of data item .
