For tapping the environment’s full potential, software should beable to dynamically adapt on demand in a platform- and language-independent manner (e.g.,by migration). Current systems have only limited support for the requested dynamics andheterogeneity. Thus, the development of such adaptive applications is still a highly complex andthus error-prone task.In the context of this thesis, the SAMProc middleware is designed. SAMProc supports softwaredevelopers in creating such adaptive applications and thus eases development. In the SAMProcapproach, applications are able to dynamically change the location and to adapt the providedinterface, the current state and the implementation in use to the particular local executioncontext. Thereby, applications are transparently and permanently addressable.
