Live and Heterogeneous Migration of Execution Environments

International audienceApplication migration and heterogeneity are inherent issues of pervasive systems. Each implementation of a pervasive system must provide its own migration framework which hides heterogeneity of the different resources. This leads to the development of many frameworks that perform the same functionality. We propose a minimal execution environment, the micro virtual machine, that factorizes process migration implementation and offers heterogeneity, transparency and performance. Systems implemented on top of this micro virtual machine, such as our own Java virtual machine, will therefore automatically inherit process migration capabilities
