The invention provides a method for migrating near data sources of computational tasks on the basis of OSGi (open service gateway initiative). The method has the advantages that the computational tasks are subjected to OSGi modularization on the basis of a computational task decision module, a computational task detection module and a computational task migration module and have merits such as flexibility, hot plugging properties and the like of the OSGi, the optimal near data sources which are the most suitable for the computational tasks are found on the premise that context management of the OSGi is sufficiently utilized, the computational tasks are migrated to the near data sources to carry out computation, and accordingly the purposes of high efficiency and low power consumption can be achieved.
